    hi my super silver haze seems to be getting worse and really need to know what is wrong with it so I can fix it.. it doesn't have root rot. recently re planted. and has big stable roots. I feed every 1 1/2-2 weeks. the sun gets very hot here sometimes 40c. is it a nutrient def?? also add in my preflower pistils seem to be going brown at the tips and my bottom branches seem to be bundeling up with leaves and not growing at all expicaly the bottom branches. and recently i have noticed the smallest leaves turning yellow and then crisping up and the bigger fan leaves just turning yellow and has stunted and it started clawing about 4 days ago and has gotten a bit worse since PLEASE help me i also maybe thinking nutrient lockout?
