Its covered in granulated DE, and mixed throughout. I've used neem and SM-90 last feeding. The pot is re-used soil no-till from last grow, so I suspect they are munching on the old roots. Fungus gnats are a symptom IMO, not a problem. If my soil microbes are healthy and thriving, the fungus gnats get out competed for food. They are also a symptom of over watering.
It's most likely over watered, 1/2 gallon to runoff after a full week, she's not drinking much. Between lowering it, shortening the grow cycle and plain water, she should snap right out of it.
I use he granular DE also in place of perlite, and will add rice hulls this next round.
AS she dries out and gets more oxygen to the roots the microbes will kick in again I would think.
