3 plants 5-6week. 1 auto went to flower she’s at 3-4 weeks in flower the other 2 photos vegging.

Saw one little gnat the other day. Then 2 the day after. This morning 3-5 so not a coincidence. My roots look cleanish. Stained from nutes but not seeing the fungus build up. Put fly paper in the tent. I germ then go to rapid rooters. Could the larva be in the rapid rooters and that’s why I’m not seeing it yet?

What to do? I run Bennie’s not sterile. But H2O2 on hand. I just did res change and really don’t want too.

H2o2 5ml/gal h2o? Into the res? Hose the roots down? Poor 5ml/1gal solution over the clay so it hits the rapid rooters.
