First photoperiod grow

Well I think I lost the dos si dos. Every new leaf grows well but ends up dying shortly after. I'm giving her another week or two of just water to see what happens. The tropicanna Banana and purple punch are going well. Topped the purple punch and LST on the TB. Turned up the sf4000 to 40% to see how they react. I might bump that up to 50% next week to keep it moving.
