hi, i am a medical provider for my girlfriend and this is my second grow in a grow tent alont with my last grow i am having the same problem, i am at the start of week three in flower and the buds are loosing thier white hairs and basically look like they are dieng on 30% of my plants,does anyone ave an idea on what this might be? i use coco coir and soul synthetics bloom, does this have to do with over watering i dont think so because i water every 2 to 3 days? or possibly poor ventilaton or light being to low? my rh are good ranging from 30-45, any advice would be greatly apriciated. what i have done at the moment to see if i can fix this problem is 1 i raised the light in the tent, 2 have started to water more often due to coco coir needing to be constantly wet which i was unaware of, and i just ordered a new ventalation fan which i hope is stronger than the one i have (which sucks), my ph i try to keep between 5 and 6.
