Ok, I've only ever used distilled water with a ppm of about 30. I never fed it anything. I keep it in a semi-sealed terrarium where the temperature stays about 80 farenheit all day, and it's pretty humid. It's about 3 feet away and off to the side of a 400 watt HPS with enhanced spectrum.
For a while it was doing great. It was responding really well to all the red light. The traps were mature (getting all pink). I was about to get it some crickets when the last mature trap closed and died, and no new ones have made it yet. They curl up and die before they even have a chance to open fully, and now the leaves are all turning black.
2 questions: 1)What did I do? 2)What do I do?
