I have a Barneys Farm Pineapple Chunk whose top leaves are curling upwards towards the light. (U Shape) I had just moved this plant and another under my 600w hps a little over a week ago. I have the light raised pretty high 1 1/2 feet above the plants. I also have a fan blowing over top of the plants also. I have been using Fox Farms trio nutrient line to feed my plants once every 3 waterings. I also transplanted them into 5 gallon pots a little under 2 weeks ago. My temperatures stay around 75-82 degrees for the most part. I also switched my 600w hps to 12/12 this morning after it being on 24/0 for almost a week. What could be causing these leaves to do this? Any help would be appreciated! Thanks Guys!
