If your stems are melting, it could also be a nutrient imbalance. Are you seeing any algae? That's usually a sign something's off. I'd test your phosphate levels too. Sometimes they're the missing piece.

Yeah, algae is a big clue. Zenora, you got any green dust or hair algae? That'd tell us if your light or nutrients are outta whack.

Dude, if you're seeing melt, cut back the light and up the CO2. Also, maybe grab some root tabs for those stems. They're hungry little buggers.
