Nice pictures. They look pretty healthy. I would make sure you don't get any larvae in the substrate. It would be a shame to have your crop take a nose dive because of bugs at this point. Those yellow stickies don't do shit in my opinion. I just use them to detect bugs only.
Looks like you are using HP promix. That stuff sucks man. Too much chance of getting bugs with that stuff which is probably why you have gnats. I aborted grows because that shit sucks so bad for bugs. Aborted grows are not good. Waste of resources and time. I find coco is far, far superior to promix. Canna coco bricks are cheap and fantastic. I ran in to a guy last week in a hydro shop in Calgary that was having issues and talking to the sales peeps. I took him off to the side and talked to him, found out he was using promix last couple of grows and his plants were never good right out of the gate. I gave him some coco and he dropped his latest germed taproots in to solo cups with the coco and he says its night and day how much better they are doing compared to promix and that is just after a couple of days of the seedlings being above ground. Needless to say, he threw out his bale of promix. Why take the chance is all I can say.
