Topped soil with layer of aquarium rock. Treated rather dry pot to 3:1 tap water:hydrogen peroxide mix, two quarts. sprayed 3:1 mix around/in plant, doused areas of activity in rock/soil with vinegar. Classic overwatering-led-to-fungus-gnats!
pot placed on riser, towel sitting underneath to capture/monitor runoff. two days after 3:1 fed pot two quarts of water with added general hydroponics 1/2/3. kept tent dry with towel replacements, idea was to saturate soil with nutrient rich water after the peroxide flush. brutal. plant is not happy.
