can anyone tell me what this is? it is only on one bud tip and its a week from chop. the third pic is the bud beside it and looks normal. humidity is at 45% and temp is around 23c.
Its not "light bleaching". This is an LED specific phenomenon and i had it happen my last grow so i spent some time looking it up. I actually mistook it for bud rot or some other bacterial nuisance. https://www.leafly.com/news/growing/white-tips-on-cannabis-buds
