First timer here. In a 4×2 tent. Saw a couple fungus gnats and also spider mites without wings so I started treating with Humboldts secret Flower Shield. Used 3 nights in a row. After second night I saw some burning of leaves but pests were still active. So I sprayed again a 3rd night. This is the results. More burn. The last pic is the damage on the leaves before I sprayed(I believe damage from the pests)
My question is, did I over due the treatment and harm my plants? If so then how do I continue treating for pests? Or are they too damaged and should I start over? I’m about 30 days in.
