Diagnose your plant. Check your runoff ph and ec levels, that tells you what is going on. Make sure your at the proper ph and ec if something is out of whack fix it and things improve. Ph tds reader is my main tool for big bud. Cheers

Is this sign of over feeding?Few of my babies in vegetative stage are encountering this problem. Some of the leaves are showing like those in photo. My guess is overfeeding the nutrients. But before I making any decision, I want to hear some professional opinions. Nutrient feed interval is per 4 days.

Slightly Brown Crinkly Tips Dose anyone know what could be causing this browning at the leaf edges? It is a bit dry and crinkly to the touch. This is only on the bottom two fan leaves, and only the very tips. All the newer growth looks fine. Nutrient Burn maybe? Should I be worried, or adjust anything?
