Spraying shit like that you Always risk problems... I just don't understand how you have three plants you don't spray bec there not yours but in your room. Usually if one plant has issues like that then all will have issues one way or another.

My guess would be that the plants you are not spraying are part of the problem.

What are your room conditions like?

Are there large swings in temp/RH between day and night?


I found the cure to PM issues was controlling the RH swings and getting a sulphur burner.

Why have plants you don't care about?

Dont be lazy, whats 3 more plants?

I sprayed over 100 tonight and watered about 60.

I hate spraying so I got a paint sprayer from home depot and use that. You can knock out a lot of plants fast with that method.
