LIGHT STRESS?

Postby rayb73 » Thu Mar 10, 2011 11:46 pm

i have this one plant(strawberry cough) it seems to be the leaves and branches are growing away from the light.its about 16" away from a 400 watt hps.wanted to know if the light can cause this or is it just the strain.i currently have kali mist,and dj short blueberry under the same lights with no ill effect.
ph,temps and nutes are all fine.i just made a trellas to try and tie up the branches that were bending down.this plant was very branchy in veg but started to do this when i put it under hps 12/12 a few days ago.
thanks

That is a nute/pH problem-- not the lights...
Strawberry Cough is a touchy grow-- Watch the pH like a hawk, and cut back on her nutes just a tad.

hello,thanks for the reply.i have never given this plant more than 1/2 strength of nutes(botanicare).i kinda figured it was a finicky plant just by looking at it.ph runoff was 6.6
i will just baby the nutes until it recovers.
thanks

sorry my bad, thats young plants and simleysmoke is right there'd be yellowing of the leaves, plus they'd be curling up aswell.
but i cant think of anything else that would make the leaves twist' if thats dosen't help then flush your soil system etc, try and find another feed that has all of these n,p,k ca, mg, and s, get some epsom salts and get a small conister of micronutrients, iron, boron, chlorine, manganese, cooper, zinc, and molybdenum. hope some of this will help
