My top leaves are curling up on the sides. can someone tell me whats going on here? These are two clones I made while the mother plant was in flower. I've had them under florescent lamps for about a month. One lady was transplanted 1 week ago in coco. The other one transplanted to DWC 3weeks. I thought it was a mag deficiency. Fed them 200 ppm cal/mag also sprayed them with epson salt. (1Tsp/gal) Its been a week and I see no progress. It just gets worst each day.

Next I thought it might be heat stress. Moved the lights 12 inches away and blew a fan over the tops of the canopies. No luck. Its no root rot. Roots are white and healthy.
No nutrient burns. I'm stumped...got any ideas whats going on with the Ladies?

Ladies are 14 inches tall
200/CAL/MAG
200 FLORA NOVA
3 tsp SILICA BLAST
1 tsp H2O2
3 drops ST
3 gal H2O
PH 6.0 DWC
PH 6.5 COCO
PPM 400 - 425
TEMP 80 DEGREES IMG_8286.jpgIMG_8284.jpgIMG_8287.jpgIMG_8288.jpgIMG_8289.jpgIMG_8287.jpg

i would say it was an environmental factor not a nutrient issue that casued this strange growth. it looks like the fresh growth got burnt by being too close to the light or having a fan blowing directly on it maybe.

other than that i can't really help you.

Yes, this is heat stress from the light. While you raised the lights, damage is done. A lot of folks say you can't burn them with CFL. And that may be the case with SOME. My 65watt and 42watt combo burned my youngins. Though your plants are much more mature in age.

QUESTION: is this damage limited only to the upper canopy? Then that's your problem,


if it's also on the lower branches ( especially on the plant to the left ) ; then can I see a pic of that?

EDIT: from looking at your pics again, it looks like the damage is limited only to the top of the plants. I would put your lights 3-4" MORE THAN where you had it at burning. ( not 12" more )

also so it looks like your girls sit out in the open??? Then it's probably definitely not an ambient temperature problem. Which would be more of a problem in a sealed setup.

Yes its the tops that are affected. What baffles me is the plant in coco is at least 6 inches lower than the DWC because of the bucket. I had a plant out in the yard that I was experimenting to see if DWC works out door. Well I had the same symptoms. Thought it was because it was outdoor or a virus in the plant. Now its happening indoors
Thnaks for all your help!

Not so fast grasshopper. You're certainly on the right track here, but if he's at 80*F and 12" from floros, even if they were CFL they wouldnt even be too hot, much less burning them.

OP, what's your humidity? I'd bet it's been on the low side of things lately.

Thanks. I've been tracking this problem for a while now. I had it once on a plant really bad and never got the answer. Recently the humidity around here has been in the teens to low 30's and the leaves did the same thing. When I misted them, it would stop for a while.

he said he just NOW moved to 12". He did not mention his original burn distance. ( if it was a burn ) also he mentions his humidity in the original post. Which I do not believe is low.

i had my 65watt and 42watt at 3" that burned my own plants following this same misconception. I believe it is the crappy 20watters that need to be an inch away.


OP:
As far as you stating that your outdoor and indoor plants did the same thing.......????
Can you be more specific in this comparison? Lastly, are you saying that your plant in coco is not burned??? Only the dwc one?

Ok first I had a dwc outside in the yard. That plant had the same curled up leaves as the dwc i have in the house. These are separate plants. I should say also that the clones were taken from this dwc outside. The only difference was dwc outside was in bloom. dwc with clone inside is in veg. Nutes were the same jus ppm was different for veg and bloom.

As for the clone in coco it is starting to so these same signs like my dwc inside. I'm pretty sure its not nute burn.
Thanks for trying to solve this. I'm out of ideas...

Oh my orignal distance that the lights were at 8 inches from the top branch.
