Hey guys! I have some problems going on with the curling of two of my plants! I have a 400w HPS light running 12/12. the humidity is usually around 50% with a temp of 25C with the lights on. With the lights of the humidity is 80% with a temp of 15C. The past week they have been curling like this and I'm not sure exactly what to do about it! The first 4 pictures are one plant and the second 4 pictures are the other plant. Any ideas or things i should check for??
