I just trimmed all affected area for and gave it more space.... also used serena spray to fight the PM. however, i woke it up from there naps. and its goign to be dayligth for them in an hour. was that a good idea?
For future reference spray just before lights go out. If you're worried about light burn on recently sprayed plant (w/lights about to come on), raise your light about 6''. Should be fine. Check out this thread. We covered PM pretty thoroughly here> PM infestation! 4 weeks from harvest! Help! Happy Growing,
