[cwesto]

ok i have a 400 watt hps goin on my single girl right about a three weeks into flowering. i grew her through veg with incondecent lights cause i could not afford MH and she experienced alot of stretching. as the pics show the upper leaves are pretty yellow in the middles of them and all cupped and curling every wich way. are they getting too much heat or light, or r they too close to the lights????? any replys are greatly appreciated..

ok i managed to cut away about 8 inches off the bottom of my makeshift pot, thus lowering the top of my plant an ever so important 8 inches away from their 400 w lights. now my lights are about 2 feet above the top. Please stop growing up plant....
my fan leaves have also been battleing a case of crispy brown tips that curl upward latelty, if anyone has an idea what is causing this along with a solution i wouild appreciate some advice. thnx to all who read and or reply

that plant looks quite supple to me maybe you could try bending it a little to stop any more hight issues?

The reason i never bent it was b/c this is my first plant and i didn't know about bending, plus it is already flowering so shouldn't i leave it unbent?? Also how far should i keep my 400w lights away from the tops in order to keep from burning again??

This is plain and simple a problem with too-intense/hot light.

your problem is defo heat stress raise light and add ocsilating fan for air movement and you should be fine

PS the temps are around 80 at light period and 70 at dark.

i have a needle type Ph tester that i bought from lowes for like 6$, my soil has stayed inbetween 6.8 and 7.2 throughout the whole grow. also i have been using FoxFarm Tiger Bloom since the start of flowering which says that it helps to keep the Ph down, so im not sure it is my Ph level...

the thing is ive had the large plant in a soda cooler from birth, i didnt think she was going to get that tall, but since i veg'd w/ incondecant's she experienced alot of stretching. i would transplant too a pot that could be lowered but i dont think doing that 3 weeks into her flowering would be a good idea. here are a few more pics that show how tall she is and also my lighting predicament.
