So I found a couple of fungus gnats. Or at least that's what I think they are. I killed them. Do you think 2 of them would do any damage? Should I get something to treat the soil just in case? Turned up my fan a lil to dry out the top layer of soil quicker. Hoping that will keep anymore from trying to come around.

Hi Jacuna, Two things you should always keep on hand. 1 is Spinosat and the other is food grade Diatomaceous Earth. Spray the shit out of them with Spinosat then once the soil dries. Dust the top of the soil with DE. -
Ok I'll make a trip to the closest gardening store. Do you think I should make this urgent? Like I said it was only 2 and I check my plants everyday so I know they weren't in there too long.Comment

Yellow sticky traps for the adults. BT (bacillus thuringiensis) for the larvae. BT is found in Mosquito dunks/bits. I've used the dunks in hydro, I crumbled them up and fed it into the media. Worked great. For soil/coco you can do the same, just crumble them up and add it to your water. I wouldn't add nutrients with that watering to be safe though.
Kingfish's recommendations should work well too. I haven't tried spinosad on gnats and I've never used DE so I can't speak to how well they work.

I'm a spaz when it comes to plant problems, so I'd already be at the store. Probably be fine for a bit, but the thought of gnat larvae crawling in my media and chewing on my defenseless plant's roots... well... you get the idea...Originally posted by Jacuna94 View PostComment

Alright here's the pictures. Hey could you guys tell me what that little white spot is? I've had one other one before this. I've only caught them when I have found a moth in there. Royal Nugs no I haven't. I wouldn't quit know how to confirm. I just figured it was them because they were on top of the soil. And I get what you mean. But I stirred around the top layer of soil and I couldn't see any larva or anything.Comment

Do you own a microscope?SSDComment

The bad news is that I have never heard of only 2 fungus gnats. The good news is that they are reasonably easy to get rid of, and they don't really do harm to the plant unless you get them bad and they damage your roots.
I had quite a few so I put about an inch of sand on top of my peat based medium and let the top of my medium dry out more between watering's. It took about 10-12 days at least to get rid of them all.
If you use sand or DE on top of your soil, it is best to water in a way that doesn't wash it all down into your medium.

what I have learned so far:
environment maters more than nutrients
at least a dab of nutrients in every watering
effective flushing before harvest is critical to qualityComment
