Hi, y’all! First time posting. I’ve got some little alocasia tissue cultures I’ve acclimated but am finding some interesting build-up on top of the pon I have them in. I thought the white salts on top were normal but I’m also seeing some red salts(?) and lint that could be mold or webbing? Also have a ton of algae going on that I’ll address later but would love insight if anyone knows what this is or what it might be. These are also growing so slow compared to other tissue cultures I’ve had.

Thanks for your help!
