Noticed some yellowing tips. I think I need to dial back the nutrients a bit. I increased them last week to see what they could handle. There is a lot more growth than I expected this time and I've let them veg longer than I usually like to but it was necessary to let them recover from my previous mistakes. Tomorrow will be a good day to defoliate and start the flip into flower. If it isn't nutrient burn, then what is causing the yellowing leaves and tips?
