Let's see and hear about your sick plants!!

[pokearound]

Thanks bad gas. Overwatering most likely is a problem. I tend to overdo lots of things thinking more is better........ Friends have hinted that I overwater. I do use a meter and will let things dry more between waterings.

I need to get back to keeping things very simple. Thanks again for the input. Cheers !

Hi folks,
Just a quickie. I'm running NFT in full hydro with Hydroton, constant feed via drippers & recirc to a 100L res. I'm using Canna Hydro Vega (should have used Canna Aqua) but I'm not chucking out 10L of fresh nutes. The Vega is meant for run-to-waste systems, so I was expecting to see some slight probs. I've got yellowing tips to the leaves but apart from that, the clones I've got growing are doing really well. Looks like a magnesium deficiency to me but my Ph is 5.8. I've added Liquid Silicon to knock the Ph up to 6.2 but I'm not sure that a 5.8Ph would cause the problem. I would like your opinions - please.
Res temp is 71 - 72. I will try to get a clear photo posted.
Looking forward to your comments.

This is an odd one. A couple of days ago this problem showed up, seemingly overnight. The plant is Sour D growing in a DWC set up under 400 watts of HPS lighting, air cooled. It's just over 45 days in. Temps have been normal, just a tad on the low side last week. The plants look healthy aside from this odd darkening discoloration of the larger leaves. Also, the affected leaves have taken on a leathery texture. Have a few fungus gnats but no other evidence of bugs.

Any thoughts?

Still growing great. Think its a nute problem. Using new "Ultra veg" by foli organics. First time i did it at 20ml:gal, this time i added 10ml:gal. In aerogarden on herb setting, used the garden before and had good results... just never used this brand nutes

too much/too little amount of nutes? lockout issue? low nitrogen?

pic 1 & 2 are of wierd spots
pic 3 is showing yellower-green leaves with darker-green veins

 

[caligirl]

and two casey jones- trainwreck x orient express x ec diesel. Sorry no pics. Im growing in 5gallon containers with foxfarm soils (happyfrog and ocean forest mixed). My water is well water with a ph of 6 - 6.5. They each are under a 600hps and i have three ocilating fans and an i keep my doors open during lights on to warm up my house and to get fresh air exchange. I feed maxi bloom and occassional cal mag and diamond nectar. I alternate nutes with molasses and plain water. The temp stays between 65 and 80 and the humidity is below 50 at most times and down to 35 occasionaly. I only water when they are dry and only enough to cuz a run off ( i have had bad experiences with over water so now i am cautious). They are in their fourth week of flowering and have been doing great - robust growth and began flowering immediatly after switch. But in the last day or so, only my jilly bean has displayed a couple yellow leaves with crispy brown edges and more of a concern -weakened stems to the point where they may not be able to support colas and wilting, soft leaves (mainly at bottom and middle of plant). The buds and top of the plant look great as do the other two plants in the room. According to the books it seems it might be calcium, or potassium def, but they are well but not over fed and the wilting mainly in middle of plant is strange and what i really cant figure out. Help, please!

 

[caligirl]

oopps first part of post was left out - sorry probably too long.

I am a somewhat experienced grower. I have gardened for decades and have about six grows (indoor and out) under my belt. Currently, I have three plants in my flowering room; jilly bean- orange velvet x romulan x cindy99 (60sat/40ind) and two casey jones- trainwreck x orient express x ec diesel (80sat/20ind). ...

Experienced Grower, Possible Zinc Deficiency.....

Experienced Grower, Possible Zinc Deficiency.....

Hey guys, please only reply if you are very experienced in dealing with nutrient burn and nutrient deficiency. I do not need guesses here, thank you.

Ok, it all started in december when I noticed a nutrient deficiency on a veg crop that is now 5 weeks in flower. The crop was likely nitrogen deficient, and to counter this, a (seemingly) knowledgeable employee of a hydro store suggested I raise my nute levels which I'll admit have always been low. But I've put out great stuff for 3 years with that formula. I run botanicare.
He put me at:
Pure Blend Grow 9mls/gal
Calmag 7mls/gal
Sweet 5mls/gal
I also was adding Liquid Karma, Hygrozyme, and Silica Blast at about 8mls, 4mls, and 4 mls/gal respectively.

930 ppms
6.3 PH
RO Water
Water 2-3 Days
Coco Soil mixture (Bcuzz and HP Promix)
Room Temp 72-80
RH 45-60% (Normally at the lower end)

This crop quickly pulled out of deficiency and has been looking epic until now.

PROBLEM #1: I am seeing VERY early stages of nute burn 5 weeks into flower now. I have not changed my nute levels since adding Hydroplex 14 days in. Incredibly small amounts of browning on the tips of most of my plants and slightly more on the sides of a couple leaves on another two plants. As of tonight the plants look completely healthy otherwise.
My ppms in flower are either at 1150 or 1400. I just watered tonight and read the ppms at 1400, which I thought was way higher than I had seen before. But I did add 3.5 mls/gal of Cha Ching tonight, so I think that spiked it.
*Do I have to flush at this early of a nute burn stage or can I just back off my nutes and if so, by how much? I am about 19 days from cutting down.


PROBLEM #2:
My new vegging crop was looking incredibly healthy for the first 6 weeks of veg. 2 weeks ago, I nute burned the tips of the smaller of two strains I have. Using my 900 ppm formula. I flushed and am out of the nute burn but am now in some kind of deficiency, possibly of more than one element.
Because it was my slightly smaller strain that burned, I decided to flush everything to keep my bigger strain from out growing the smaller ones. I am finally getting vertical growth again, but my tops are not looking good. They are in 7 gallon pots. The smaller ones are at my belt height, the larger are at my navel and slightly above. Lights are 1000's and are two feet away.

Actions Taken:
I flushed everything twice, then immediately saw all green healthy tops turn yellow. Then slowly shriveling for two weeks since.
After Flushing, I backed off my ppms. Am watering the smaller group that actually got burned at 780 ppms. I did one water on the larger group that did not get burned at 820 and now they're being watered back at 900.

I do not believe I am still dealing with a nutrient burn, but I could be wrong. I see very little browning on tips and the ones that definitely did burn have regained some light green color at lower ppms.


SYMPTOMS:
Yellowing Tops
Shriveling Tops (leaves are folding in half like tacos on each fan)
Stunted Growth
Some Heavy Limbs have broken at the main stalk due to not supporting their weight.
No discoloration on bottom mature leaves, all is a healthy normal green.

Nutrients:
Normally I never have used Botanicare's Sweet in veg. The employee recommended I did for whatever reason/deficiency I was in last crop. I decided to save money and not use it in veg this round. This was my veg recipe leading up to my burn:

Pure Blend Grow 9mls/gal
Liquid Karma 8mls/gal
Cal Mag 7mls/gal
Hygrozyme 4mls/gal
Silica Blast 2.5mls/gal
PPM 920
PH 6.3
RO Water
Water 2-3 Days
Coco Soil mixture (Bcuzz and HP Promix)
Room Temp 78
RH 40-50%

I've been seeing no improvement, but a slow and steady worsening. I talked with two different employee's at two different hydro stores, and both of them thought that the tops folding in half would be due to excessive magnesium, so to back off the Cal Mag. One of them said to discontinue the Sweet. Tonight 1/27/13 I watered at:

Pure Blend Grow 9mls/gal
Liquid Karma 8mls/gal
Cal Mag 3mls/gal
Hygrozyme
Silica Blast
PPM 920
PH 6.3
RO Water
Water 2-3 Days
Coco Soil mixture (Bcuzz and HP Promix)
Room Temp 78
RH 40-50%


Hypothesis:
This last crop and this crop are both the first time I've ever had to deal with nute burn or a deficiency. So I have very little idea of dealing with deficiencies.
From my internet research the closest deficiency pictures I'm seeing, to what I actually have are yellowing tops like an Iron deficiency, and folding tops like a magnesium deficiency. As previously stated, all of my undergrowth is completely healthy.
A magnesium deficiency does not make sense to me, seeing as they were getting 7mls a gallon of Cal Mag and at a fine Ph of 6.3. However, I was not adding Sweet like suggested to me on the last round, and Sweet does have some Magnesium in it....

**My newest and most up to date theory is a zinc deficiency.
I have stunted growth, seems to be regaining now. Yellow top leaves, with green veins, tops shriveling and leaves folding, bottom foliage unaffected....



*Other possibilities,
*10+ days ago, we had a heat flash where I live and I walked into my room being 87 degrees. It had probably been that the night before and part of this night. Since then, it's been typically 78 degrees and not hotter than 81. I've had to grow entire crops at 84 degrees before and was able to pull it off. Seems like they should be back to normal now that temps have been down since.
*Over Watering. I've been waiting every three days usually, but sometimes two days. If I do two days, and they are wet, I give a lighter water.

i would say whit plain water they bounce back better than whit nutes, you have to keep on eye to hole coloration of plant and judge by that besides looking how ph and ec levels(ppm) change in reservoir.
for that you need water meter too, as equal amount of water has replaced to volume of original amount of reservoir you should see if ec is climbing or going down - if it´s going down you have too weak solution if its going up you have too strong solution, if it stays almost in same whit little drift to non, then it is strong enough.
are leafs cupping up or down?
is i were yo i would check the temperature of tops, those pointing infra thermometers are good for checking leaf temperature, those other meters whit are lying most of the times range of 1-4 celcius degree, what can cause things.
if the ph is going down, then you might have bad bacteria infestion.

i thought you were talking about hydro,sorry... morning tokes he heh

CLONE WARS HELP!

CLONE WARS HELP!

Ive been having major cloning issues since november.have switched to a completely new system that shows no sign of any nasties.using ro water from the grocery store and temps are in the 78-80 degree range.working with super silver haze and today is day sixteen.the cuttings are teasing me big time because i see nubs but they wont come on and pop! the bottom leaves are starting to yellow and some have even begun to twist and stand straight up...weird.one cutting even looks like it was burned but im not sure how without any nutes...running 1oz of 5mg/gallon of pool shock solution in five gallons on this new round because of horrible naties in ez cloner on past runs.Stems still feel hard and there is no sign of the mush.overall the cuttings are perky but this twisting and spotting issue with No roots by day 16 is stressing me baaaad.ANY advice would be much appreciated.




This is the one that puzzles me the most...is it burned???

 

[babbaganoosh]

oh and ph is 6-6.3

 

[niggle]

Hey everyone , I'm starting a grow from seed, just two plants, one bubblegummer, one super lemon haze. My problem is the slh has stopped growing once it sprouted and the two leaves have gone almost all brown.

 

[babbaganoosh]

niggle,ive had the same problem with slh.

 

[niggle]

Thanks, I lost the seedling but I popped another in some water which kinda sucks. I hope it will pop soon so it can catch up to the Bubblegummer

Hello fellow growers!

I am experiencing some nasty problems with my darlings. They were doing just fine until some time ago, when they developed some nasty symptoms. The mixture I use is 60% organic soil, 20% vermiculite, 10% perlite, 10% coco fiber. Everything was store bought, which, I understand, was a rookie mistake, but I am already in this like so, so, please, keep the comments constructive. Anyways check this out:

This one developed some PH problems, which were resolved just in the knick of time, but it still got scarred pretty badly. Poor thing...


This is the same one, but I don't think this is PH related. From what I can guess it is something zinc related, but I can not be sure. Give some feedback on this one, will you?


This might be PH related, although I don't see why, I've been pretty careful with the PH stuff since the other one fell ill. Looks like high PH to me, but still - spare a word on this one as well.


I just don't know what to make of this one... Terrible, hurts right in the chest to see it like this. This one needs your help!

I am pretty sure this is zinc deficiency, but I can not be sure, and I don't want to act on impulse, before I consult a senior grower. What do you think?

Thank you!

 

[babbaganoosh]

what technique did you use for the bubblegummer to take off?im getting ready to try some more seeds bc my cloning is going terribly...
