Yeah.. don't do that. If you have Fugus Gnats, treat your soil with MicrobeLift liquid BTI (Amazon). Mix in 1 drop per 2 gallons or 1 per gallon in your case since you only have a few plants. Get some yellow sticky traps to catch the adults. The Mirobelift will kill the larvae in the soil. Fungus Gnats don't mess will your bud, or plant material, they're just annoying. But, the larvae will feed on your capillary roots. Wash all that shit off of your plants (during lights out), and never spray anything during lights on, you'll burn them, and also all that DE on your leafs shade out light and decreases photosynthesis. Today's lesson has been brought to you by the letter M........... What? None of you somebitches ever watch SesameStreet?

Otherwise, your plant looks good size for the age.
