WOW! Is that a mushroom I see in the 3rd pix? On the right hand side? Not so sure that is a good thing. You may want to remove it before it lets go of spores and reproduces. But mushrooms require super damp conditions. Do you have enough perlite in your mix? I can't tell but is the last plant in a clay pot??? If so,,,,,they can get waterlogged and slimy if the soil mix is to heavy. Maybe that is the problem. Anyone else??? Rosie

Mushroom is def the first thing i noticed and would mean wayyy to wet. It does have a really tight crown, maybe Irina will have a guess as to why and the browning...

Yeah,,,,unless you are growing for beauty AND food at the same time! IRINA help??? Rosie

I agree with you guys - it is way too wet. Usually i see this dampening off on young leaves of Streptocarpus - rarely on AVs. The good part - it is a cultural problem, not a disease. So repotting to a mix with plenty of perlite, in a smaller pot - and keeping the watering down - may be a smaller wick - not the whole yarn, but half of the threads - if it a 4 ply yarn unravel it to 2...

Regarding Little White Mushroom - it usually means there are wood chips in a mix - and we do not need any wood there.

Will hop on it. Thx Irina. Always afraid I have a pest. Glad to hear simply moisture. Hope u r well!
