I've got a Cape sundew that's like 1.5-2 years old that I picked up last summer, and for some reason after I've moved it outside a few months ago it's slowed down in growth and its new growth is starting to turn black. I did repot it about 3 weeks ago into a bigger pot since its roots were starting to come out of the bottom.
New medium is the regular 50/50 mix of perlite and peat moss. I keep it in a tray of distilled water. It's been in the high 80's all month long so far here in Georgia. No fertilizer or anything.
Is it suffering from heat stress or just too much sun? Acclimation to repotting? Acclimation to the weather turning super hot and sunny outside?
