[20north]

so my chemdawg as black spots on the leaves at the tips i was thinking it was a nasty mold like PM or something but i have a dehumi should i have an ozone generator i heard those can help

PM is whiteish.

Could it be nutrient burn? Never really seen any black mark on cannabis before.

Could the tips be touchin the light or ballast? maybe some burnin goin on?

Never heard of or seen black tips...

Hope you figure it out...

would a bifenthrin greenhouse bug bomb be the cause of this? i used one because i had so many moth lava things and it drove me crazy

 

[Illegal-Seed]

Possibly. Because black spots arent normal.
