I noticed I had a problem with aphids so I decided to purchase some Neem oil to kill those soft body pests. I Mixed 1 liter of water with 15mls neem oil and a lil bit of dish soap. I sprayed the plants in their entirety with the solution 5 mins before the lights went off and 10 mins after (with a 40w cfl on to lightup the room). Today I noticed that some of the hairs are starting to turn brown and curl up. Should I not of sprayed the buds? The plants are only 3 weeks into bloom so I know their's still a lot of time for growth and development. I'm just concerned with what I should do (or should of done) and what I need to do to counter-act any harmful effects I might have caused.
