yeppers. Potassium bicarbonate works good at this stage, once flowers form it will burn pistils though. Whatever you end up using, test a small area first, to be sure the plant reacts okay to it. Good luck!
Do you have any suggestions for use during flower, that won't burn the pistils? Currently using a mix that includes potassium bicarbonate (first time grower)
Curious to hear what others are using to combat/prevent pm during flower.

I’m using plant therapy, is it a loss or can I still bho or press it, maybe hash?:(
Also, at first I thought it was from the condensation dripping from the plastic and then evaporating, leaving minerals or salts from the roof or rain or whatever behind, and it still maybe, plan to send a few in to get tested, as I’ve been spraying plant therapy for over a month e3d for pm, and it’s not spreading, any advice would be greatly appreciated:wall:
