This plant is pissed, wtf is going on!

[summitoker]

This is growing in 75/25 coco fiber/happy frog soil.
I dont know the exact genetics, its a seed pulled from a nug of sour diesel.
She has been watered with ro water, cana coco ferts, ph set to 6-6.2
Growing under a 600 HPS

What i noticed was a lot of yellowing like she wanted nitrogen. So i gave her a bit of biobizz grow. 2 days later is what you see here. All the leaves were pointed up towards the light before, now they are all curled down with brown dead spots all over.

 

[mexilandrace]

how long into flower?

 

[NiteTiger]

How often are you watering? Coco is your primary medium, and when handwatering, should be watered once a day. Also, have you checked your runoff PH recently?

In the future, I wouldn't recommend mixing hydro and soil.

 

[summitoker]

I water every day. Every 3 days they each receive a gallon, every day a liter or 2.
I have not checked the runoff PH, but i always ph before watering. The mix of coco/happy frog was supposed to be a easy version of moonshine mix. She has been under 12/12 for about 50 days, has always been a very slow grower. I was going to start flushing in about 10 days. Does that look like to much nutes or???


Heres a shot of the whole garden...they all love the coco/soil mix for the most part.......... The yellowing on a lot of the plants you see here is because they are about to be harvested...not the same as the plant in question.........

Looks like a chemical salt buildup.

Why did you feed an organic nutrient when you've been feeding mineral based coco nutrients? Was it the only 'grow' nutrient you had? You don't want to be feeding too much N at 50 days really, you want them to be using up their N stores at that stage, but they've yellowed too much too early.

In any case an organic nutrient like Biobizz Grow won't be too helpful in a predominantly coco grow, because it relies on micro-organism chelation to release its nutrients in plant useable forms. If you've been feeding predominatly chemical nutrients, these will have destroyed any substrate micro-flora or reduced their numbers due to inavailable food.

The first thing I would do is check the TDS (EC/PPM) of the run off and then consider watering just plain ph'd RO water with 10-20% run off and then a 1/2 dose feed of your Coco Canna nutrients and see where you are with them then.

 

[stinkyattic]

Even with a coco-specific nute system, if you are running RO water, you STILL have to add calmag to the source water up to 250ppm before mixing nutes.

Your plants are suffering from insufficient Calcium available to them.

 

[moonymonkey]

watering can definately afect calcium levels.....peace

 

[summitoker]

so you guys are saying that the canna coco killed all the life that was in the happy frog soil, which is making organic nutes like biobizz unavailable? When i gave her some biobizz grow it was 1/4 strength cause i didnt want to over do it..
I have the following nutes/supplements available right now to do a flush...what should i pick if anything? I dont think any of them have much calcium.
canna coco B
bio-bizz grow/bloom
BC boost
humboldt master A/B(organic i think?)
earthjuice microblast
pro-tekt silica
cannazyme
Rush CalX
alg-a-mic
topmax

It's pointless using an organic nutrient with a chemical fertiliser when you haven't cultivated the micro-flora. If you wanted to boost the N levels, a dose of Fish Emulsion would have been much more effective as it's more immediately available and doesn't rely entirely on micro-flora to break it down. Fish emulsion greens up plants (adds N) faster than anything I know.

Be careful how much N you give those plants so close to harvest.

It's not Calcium for 3 reasons -

1) None of those leaves show any signs of Calcium deficiency and in any case you'd get Mg problems before Calcium ones; Calcium affects the newest growth first, not old fan leaves.
2) Calcium deficiencies are extremely rare in inside grows;
3) Canna Coco contains calcium.

If you want to add some Calcium when you flush, flush with 50/50 RO/tap water. RO or distilled doesn't matter.

What do you mean by cultivating the micro flora? The happy frog is loaded with beneficials, unless you mean in the nute mix itself.

Regardless of what is going on i couldnt really wait anymore. SO she was just flushed with a gallon of ro ph'ed to 6.0, (runoff came out at 6.0) than a gallon of 3/4 strength canna, bcboost, bioboost(beneficials), and cannazyme. I hope this straightens her out.

Wrong, you should, as I have noted seeing your posts in other threads, brush up on your plant damage ID skills, and not just pictures you found on the internet, which are occasionally misleading.

2) Calcium deficiencies are extremely rare in inside grows;

Wrong, I see them on the plants of people who like to water with distilled water and/or don't re-pot on schedule FREQUENTLY.

3) Canna Coco contains calcium.

Correct, to make up for a chemical scavenging interaction between the coco and available calcium, but the level is ONLY enough for that difference, and not enough to make up for demineralized water of any sort.

If you want to add some Calcium when you flush, flush with 50/50 RO/tap water. RO or distilled doesn't matter.

That doesn't add enough, even disregarding the fact that tap water Ca content varies widely.

Just add your calmag.

 

[theHIGHlander]

i thought it looked more like cal/mag def ...i didnt say anything though as am still learning with sick plants & didnt want to give the wrong info...

we tip bro,
copy and paste the sick guide for plants.
then people like stinkyattic/mynamestitch and few others will be more than willing to jump in and help you out ...(just help them out with as much info as you can)

the last thing you want in times like this is bad info. and when it comes to sick plants theres no better people than stinky/myname,,thay sure know there shit about sick plants

am sure all with be good

keep it green

back to basics mate. dont complicate it

do a clean water flush with ph adjusted water. your ph should be 6,3 in soil atleast, coco im not sure, but you should probably not go below 6,0. flush atleast 2 times the potvolume, so if 10litre bucket, then flush with 20litre water. measure runoff and adjust the soil ph. sometimes when nutes get built up in the pot you can get a souring effect in the soil over time.

use the canna coco, its good full nutritions, ill vouch for the canna full nute products. and now that you have problems, you want to use as little product as possible so you can see the effects of the product you are giving. the full nute products WILL produce green and healthy plants without any additives normally. so if you are not getting that result, remove all possible flaw factors and go back to basics then add them one by one.

so, flush and then back to 1,5-1,8 EC full nute solution with 6,2-3 ph dont go below that, and dont give any additives or boosters yet.

then if you are sure that your nute levels and such are good.

you need to check your equipment also regularly. especially ph-pens and ec meters. then re-check your temperature levels and growing climate, and remember also not to over-water. roots needs air also in order to efficiently absorb the nutes you give.

you can give enzymes if you got that with the flush, but allow some days after flush for the pot to go dry again before you feed.

basically this is what i always do no matter what the problem i have is, and it seems to work for me.

if you are worried that your problem might be over-watering, then just allow the pot to dry down, and then give the basic full nute solution with some enzyme.

Be warned, as this always happens. Whenever you ask for advice and diagnosis in the Infirmary, you're going to get many solutions and opinions.

Don't try to implement them all at once. You'll end up not knowing exactly which solution worked. Start with the basics.

Get that PH down to around 5.8 - 6. Your PH is just high enough to touch the lockout zone. That means that the cal mag would work briefly, then go back to the same state. Then, you've still got a PH problem, and now, when you get your PH right, you've got too much cal/mag in your solution.

When there is a problem, any problem, always start with PH.

I do not see how you can water every day like straight coco with 25% soil added to the mix

Just got finished with a 50/50 coco ocean forest run could not get a watering method down for shit

Never again

[summitoker]

Learn to water by the weight of your pots.

Look at this pic its from several days before the first pics i posted. See how all the plants are happy leavs reaching for the sky, but the plant in question is clearly visable, right hand side with the droopy leaves?




She was flushed again yesterday, 2 gallons plain water phed to 5.8 than a gallon of 1/2 strength canna , silica, and cal mag. Hopefully in a few days she looks better. Runoff at the end of all that was 5.9. She will be all alone in the tent in a couple days, besides the haze....

 

[maryj315]

I do the lift the method it is all i know






Took interest in this thread because that one plant in the middle gave me the same problem as yours this was taken at day 30 some thing

Notice all the other plants are nice green except this one

Mixing coco and peat the lift the pot method did not work the same in my experience the plant would stop growing in need of water but the pot still felt heavy

I think my problem was how often i was watering

Mj

 

[Kinderfeld]

salt build up (over done on nutes) which caused some lockout and all probably casue by inconsistant ph, sure its at 5.9 now but what was it 40 days ago? No body knows...check your runoff every other or 3 waterings.... I would flush really all you can do....

 

[mexilandrace]

has that effected plant put on any weight in a while?

Its so late in flower its not really worth screwing with, least I wouldn't, by the time you got it fixed it would be time to flush, just flush now and harvest early.

sick plants don't fill out like they should anyways.

just my opinion
