I followed Ross's most excellent advice and repotted my Tolu. Genting 'Volcano' in a net pot in charc chunks. I was a little sceptical at first, but it's doing great and kicking out a new growth. The new growth looks much better than the existing fans. They looked funky when I bought it from the grower. It was in a 1" thumb pot. It's much happier now. It's hanging from the top of my grow rack and is getting as much light as I can throw at it.
