yes i would stop nutes, flush with plain water (enough water for it to run out of the holes in the bottom of the pot). then let the pot dry for a few days. what is your soil ph, if you don't have a ph meter go buy one, they are very cheap, anywhere from five to ten U.S. dollars. let the plant dry out until the top two to three inches of soil are dry (soil moisture meter five to ten bucks too). then i would flush one more time with plain water three to four days after soil dries out. looks like nute burn, plants look a little small to be giving nutes too soon. my plants are in foxfarm soil, haven't given nutes yet, they are green and healthy, about two feet tall and bushy, just use plain tap water that has been sitting out in opent for 34-48 hours of longer. what type of water are u using, tap or bottled? the ph of the water can screw up plants also, so a synopsis after the rambling message, buy a ph and moisture meter, stop nutes, flush twice and let them heal, peace

did the plant grow into the light? if the cfl touches the leaves it will burn it, it happened to me. a good test is put your hand between the lights and the plants, if your hand feels warm then back the lights up a bit. did you flush the plant? could be nute burn also, especially if your soil medium has nutes in it also. any updates?
