Is this due to root rot? Temps? Or something else? Leaves have been curling down due a few weeks, and now they are starting to droop and dieback quickly over the last few days. There is some new growth still though. Do I need to uproot it and check / cut roots?
I’ve found that adding an inch of fine aquarium gravel on top of the soil and again in the drainage trays (enough to cover the drainage holes) eliminates gnats in a week or two.
