Any one know why my leafs on the top are pointing up? I don't have a mag problem, the light is a 600W at about 18-20" from plant and my PH run off is 6.6 as of now. I don't have a working PPM meter so it could be over fed still as I only flushed with 2 gallons of water and it is in a 2 gallon pot. I have not had any significant burning or anything. I am wondering if it is my PH up as I am using potassium silicate and I have to use a lot to raise my nutes. I have to use 1-1 when feeding with tiger bloom.
