I have had a large Bolbitis Heudelotii growing in a tank with not other plants for nearly a year now. It was growing slowly but surely. The lighting was low and I used minimal ferts because I didn't want an algae bloom. About two months ago I began dosing via the EI method on my treasured Bolbitis. I didn't see much of a difference. To make a long story shot, I have ignored it for about a week and now I'm noticing some serious melting. I honestly almost cried. The rhizome appears to be in good shape but those beautiful deep green leaves are disintegrating. Please help!!!!
