Plants refusing to flower

[Backdoor man]

I have four feminized Super silver hazes all from seed sown at the same time and developed in the same environment, i am now at week 6 of a 10-11 week harvest, problem is two of the four are not yet showing any significant flowers, what pistils are showing are extremely thin and small, hardly visible really, yet the other two plants are blloming excellently showing large long white pistils and now with trichomes becoming visible.

Does anyone know how this can be?
Is is genetics?
Is there any point keeping the two lazy bastards, are they going to be ready sometime this year? They look like i only switched to 12/12 last bloody week!
Looking at the plants, id say that if they started to flower normally from tomorrow they'd need something like 3-4 weeks at the least catching up, time is something i do not have, i need a regular harvest to keep me in supply, i cannot afford to waste months flowering plants...
Im confused and worried... help!

You have any light leaks going? That are on that side closer to the plants that are not flowering?

They all from seed? You still using nitrogen? How much if so?

Need some more info about your grow........

Need to know what your setup is like... what equipment you are running and such.....
Never heard about them having flowering issues... I seen a lot of people grow this strain over at overgrow......

There are definetly no light leaks, and yes i already thought to move them about just in case that was something to do with it.
My set up is basically a resin made shed, that is situated in my garage lined with mylar and insulated, there is fresh air being pumped in and extracted, im growing in Bio-G-Power soil, using Canna nutes under a 600HPS.
Ive been feeding under the recommended doesage, and all four palnts look healthy with no sign of nutrient deficiences.

The only problem i have with this environment is maybe the temps get a tad too low during the dark period, other than that i cant think of any problems with it.
There seems to be two phenos that are very indica like, short, squat and broad leafed, ive noticed that on both of these the stems leading to the fan leaves are a deep red colour, both of these phenos have been topped, the other two are typically sativa, tall and slender. Thing is its not one particular pheno that is struggling, i have the tall sativa and one of the shorter indicas both flowering nicely, yet the other two are doing nothing

 

[Dr Pepper]

Just keep the two good strains alive, the others sound defective.

 

[Core]

you could even have 2 runts for all we know.....no pics?

 

[Backdoor man]

Sorry no pics im afraid...
There is still no more development in flowers, though they're both growing quite vigorously
With regards to nutrients, as i say ive fed lightly with these, i gave them all a feed of canna terra vega at about 3/4 the recommended dosage once when the plants were about 3-4 weeks in the soil, i noticed slight nute burn on all but one plant so i carried on feeding just water until i noticed the fist flowers forming - still a little concerned about burns ive only fed very lightly with the biocanna bloom.
Only today have i fed the two healthy girls a full dose of bloom, due to the fact that there has been very little flowering by the runts today was their first ever feed of bloom at half dosage.

I'll keep them in the room and see how things go, if theres still nothing happening by the time the two healthy girls are harvested, i'll get rid of the runts and make sure my next grow is a quick flowerer.

How do you expect a plant to flower if you have only fed them next to nothing? Canna line nutrients you can go by there feeding chart so you using 3/4 there dosage...... it's like feeding them baby food dude.

You grew those 4 plants from seed right? Well, reason why those 2 may not be growing is because it may be more hungry pheno of SSH.... you gotta feed weekly man every 7 days.

What soil was you using when you used 3/4 the dosage and showed burning? Sounds like to me you had not burning but a deficiency.....

never heard someone burning there plants with the small amount you used around the timeline you gave.....

unless you used like 3/4 dosage in like 1 liter of water or something like that.

How much water did you mix it with?
But dude you gotta feed more; plants good doses of P and K.... do you expect to grow if you can't eat?
Your plants can't produce flowers when they do not have enough P and K and a little bit of nitrogen early in flowering.


has been very little flowering by the runts today was their first ever feed of bloom at half dosage.

That is why they are runts and not flowering; no food no flowers

I had been told that the SSH was particulary fussy and not too keen on being fed nutes, i suppose i was maybe a little over-concerned about this and i may have been a little too soft on them. Thing is though, the plants have no sign of any kind of deficiency, all four are as green as green can be, i took this healthiness as a sign that the plants were doing fine on there own and didnt really need much help.

Ok i'll feed them full doses from now on, thanks for the advise, we'll see how it goes.

We have seen plants from the AUH#2 that didn't really want to flower,, and the odd SSH does the same thing. These plants soon find the compost bin.

How do you expect a plant to flower if you have only fed them next to nothing?

This statement is very misleading!!! (sorry no offense)

For example, this plant was never fed ANY nutrients,, ever... but still managed to be fast flowered OK... lol



Sure thing,, if you're growing lowland sativa,, then they may need some extra feeding every now and then to help them mature,, but this has got nothing to do with photoperiod and the advent of flowering. For example, in places like say, the Hindu Kush range or Afghanistan, where soils are heavily depleted of natural nutrients, a reduced photoperiod induces sexuality in cannabis,, not what's found in the dirt.

A healthy soil mix should contain everything needed for the first 2-3 months of growth. When growing indoors this means plants need very little application feed to sustain growth,, cause it's always better to start slowly leaching nutrients from the plant during the final bloom. (commercial gardening compost containing slow release ferts lasts longer,, 6months).

peace out

N.B Shooting soils with steroids is OK,, but only if you want your plants to look like the Incredible Hulk

 

[MynameStitch]

Doc; that is if you rely on your soil to provide you will all the nutrients; but in this case he is not.

Backdoor post your pics of your plants; what nutrients are you using; do not listen to the back of the bottle unless it's made for cannabis.

Full dose could be too high; I never said use a full dose dude.

A healthy soil mix should contain everything needed for the first 2-3 months of growth.

This I will have to disagree with here; I will give several reasons. Using brand name soils that have additives like FFOF soil..... only sustain a plant up untill 23 to 30 days and even then that is pushing it. In order to make your plants live on the soil for 2 to 3 months I would LOVE to see how that plant turned out. You would have to keep your plants SMALL and veg them for like a week and put them into flower for you your quote to be true. Actually looking at your picture.. see how small your plant is in flower? A plant only absorbs the amount of nutrients it needs by it's SIZE. SMall plants can live in soil longer; bigger... need fed.

So there is just no way; moonshine mix is a different story... but right now I am talking about other things.

So plants need food; how do you think plants bloom if there is no P and K?

Ya, most of it's to hot for cannabis to begin with if you want to kill your plants ehh thats ok. Most people Dilute it or skip it al together as it's just not made right for cannabis.
Timed released ferts can release ferts at different temps too; colder temps release more
which can burn them even quicker; you can't judge by using time released ferts; anyone on this sites know's time released ferts are bad to use...

So I will have to disagree with your whole post.

...In order to make your plants live on the soil for 2 to 3 months I would LOVE to see how that plant turned out.

Here ya go (kachina, sensi star, bubbledust):







All these indica/sativa plants were grown in Bio Biz all-mix soil,, some perhaps got an extra shot of food at around 30days 12/12,, but as a rule they didn't receive any additional feed during their life time. They managed to survive on what was available in the soil quite happily enough.

The method is indeed fast flower sog style,, 30days veg/70 days bloom,, so the buds grew on the available P & K that was already present in the soil.

(commercial gardening compost containing slow release ferts lasts longer,, 6months).

This was a contrasting example,, the reason why the text is in brackets ().

Correct. home depot compost is usually of the wrong soil pH and slow release ferts are unsuitable for indoor cultivation. we agree :friends: This was one of the points we were trying to stress... Cannabis is foremost a weed,,, then a veracious herb,, then a pet-project.... hehe

Organics is all about what's already in the soil to begin with IMO,,, only then do we think about feeding the soil again

Please remember "we are feeding the soil, not the plant" [HHF] :wink:

Hope this helps

Anyhow, sorry to crash the thread. Let's get back to these plants that don't/won't flower.

Certain sativa based strains do seem to dislike the whole notion of flowering.

IMO this is genetic and environmental,, and is perhaps related to air and soil temps, and overall humidity, rather than the available P & K. Soil type therefore has plenty to do with it, since if the roots aren't happy, neither is the plant.

To add: some equatorial sativa strains (e.g. Zamal) act more like bi-annuals than annuals under natural conditions, so perhaps this is a genetic throwback that ensures the possibility for natural back-crossing. i.e. last years female gets loaded from the following seasons male. ( )

Either way it seems that this 'phenomenon' is reoccurring within certain GHSco lines these days,, you can feed hell out of them if you wish,, but those Laos strains just don't want to play the flowering game.

peace n flowers

Look at the size of the plants they are a little over 12 in tall; give them a good mixture with that size you won't need to feed. BUT you did feed once so therefore there was not enough to sustain it.......

THe plant is turned over to flowering by lighting changes more than anything else; giving it P and K is not going to turn it over to make it flower...... there are auto strains but I am mainly talking about non ones....

So the point is; the thread starter said his 2 was not growing.... he also stated he was skimpy with them on t hefood...obviosly there is a problem. Plants grow with food ( I know you know that) so how can they produce without eating enough?

Naa man we are cool Just everyone has different opionions about things and I always say people need to express it; we are just having a conversation about things we do not agree with

No flaming, just plant talk

 

[KUSHEATER1]

check bulbs and any holes or cracks I had that problem took them a month to even show hairs and these where clones get in nthere and find the light leaks and check the bulb,As for feeding I have learned that less is better read the plant I grow dwc and I only feed once in veg and read her all the way through flower some ladies ask for more...







forgot the harvested kush nug

 

[MynameStitch]

I grow dwc and I only feed once in veg and read her all the way through flower some ladies ask for more...

Feed once? Thats nuts; to keep a healthy system without salt buildup you are supossed to clean out your system every 2 weeks max.

I do not see how you can just feed once and sustain a plant in DWC.... sorry I do not believe that. I could get anyone who grows DWC in here and they will say thats crap; plants take out nutrients in the water and thus you have to keep the PPMS stable or adjust them more when they get bigger. Unlike soil plants rely soley on nutrients in the water so I am said to say how the hell you keep plants alive with one feeding in DWC.. that is a bunch of BS; I grew hydro for a little bit so I know.

Dude, recently I heard soeone say water your plants everyday was crap.. but now this one takes the cake... feeding once in DWC? Biggest BS ever.

 

[KUSHEATER1]

no BS I run bio so I don't change rez out but 2 at begining of flower and when i flush ,I never have to bs anybody I only gave my .02 and it's not worth shit so if ya wanna use it then do if not then don't ...
and like I said if she begs for more then I blast her

 

[DocLeaf]

Look at the size of the plants they are a little over 12 in tall;

Those plants were all over 1.5m tall :wink:


This plant sits over 4ft tall in soil,,, only had x1 feed of seabird guano during veg, nothing during flower.

This morning ive noticed one of the runts making some progress, she has began to throw out some normal healthy looking pistils
The other hasnt

I once had a problem with a light leak and i learned a hard lesson as a result, there is no way there are any leaks in there, there are no street lights near and at 8pm when the light goes off, nobody enters that garage as i have the only key (to the backdoor hence my name).
As i said, the only problem i can find with my set up is that the garage can get a lttle chilly at night.
Im not saying im an expert grower, ive been at it for years on and off, but its only since joining this forum that ive become a bit of a "weed geek" learning about the technicalities ect.
I wouldnt say i was a novice though either, ive been observing the health of plants for years by watching them and learning through trial and error, though it must be said that this is my first go at a haze/satvia dominant, prior to this ive always grown -Afghan's, skunks and a few Uk cheese's.

Im beginning to conclude this must be genetical, after doing a little more research, it does seem that the GHsco Hazes are known to do this, the fact that two are doing fine and two are not yet they've been in the same environment from day 1 does suggest this.

 

[DocLeaf]

That sounds about right,, good judgement

 

[KUSHEATER1]

Like I said only twice I only veg for 30 days or so and I don't feed until week 2 and they take off great I add only water back until I begin flower and thats when I add flower nutes with rez change and the plants are about 12-14 inches tall hungry and ready to do my will and burst open with flowers every where.It really makes me smile when I read how guys jump all over people that don't grow the way that they grow or the way of the norm they try to blast you I'm no liar check out Mike118 on ***** I tell the truth, this was the first time I was on the end of anyones rants but I guess it happens the way I grow will work well but temps are very much in check and I truly read my plants I believe that we humans just use to much to try and enhance things too much every strain I have comes in clone form so I don't know have fun gents and just grow safe...
