maybe its because your lights are on the side of the plant instead of above it...based on your pictures the light seems to be directed towards the portion of the plant you claim is doing well, but the top, where the problem is, looks like its not receiving nearly as much light. upon further inspection it looks like you have a little room next to it they are normally stored in... if THIS is the case then there are most likely lights mounted above.seriously though, the plant looks very healthy, leaves will often do that to take in less lighte and release more oxygen. by doing curling like that the stomata can release as much O2 as possible. I think your plant is very hot and that, lower on the plant -where it is cooler- the stomata are not releasing as much O2 and are, as a result, looking normal. HPS puts out a lot more heat than MH... I really think you have an overheating issue. if it continues the leaves retain their color but dry out and turn to dust when touched. this has happened to me in the past. very depressing, indeed.

if you read in the plant problems section it says if the leaf tips are curling up that it may be a mag. problem or toxic salt build up?? looks like a mag. def. and possible lock out, I would flush it with a mild epson salt mix,this way if it is salt build up the flush will take care of that and it will also have the mag. there if it needs it.Im no master indoor grower but thats what I would do. good luck

the light are above the plant i i toke it out of the tent just to get a good pic. the temps in the tent is at 70F and the reflector is 18" from plant tops release bearly any heat as i got a good fan on the reflector.

do you boys think it could be due to much wind? i got 4 4" fans and 1 6" fan the 6" is was blowing directly on the plants and it rotates from left to right.

Keep the fans less nutes homie. I feed every other time and they love it. Make sure it has an open root system when inducing onset, so since you switched to 12/12 the plant wants to shoot so its roots 2. transplant into somithing about 2 gallons bigger. Do not feed your plants every watering they need to be flushed so the nutrients dont build up in the soil. Easy way to keep that from happening is to foilar feed or spray them. Be sure to not spray under lights as your plant will burn. You will be fine just transplant and give it a couple of plain waterings. I have a plant thats doing this only because she is in to small of a pot.

Hey nas here to help my man. You say your temps are 70. Good. Hows your rhumidity levels? First thing that came to my mind was there getting hot. They really dont look that bad to me. It normal for your leaves to cup somewhat to help absorb light.

There was one pics that i thought i might have seen a bit of dying leaf tissue. Could possibly be a bit of over nute?. Very low humidity can cause the leaves to dry up some aswell. Your sure you never got your light to close for comfort for a bit?

looks like heat stress to me as well, but if temps are 70 then it shouldnt be that, how hot is it at the tops of the plants, if it is happining at the top it could be to close to the bulb
