I was trying to find online the correct soil requirements for these species but I couldn't find an exact answer. Do any of you guys know? My undulata are starting to get funked up new leaves...coming out distorted and whatnot. The leaves have always been yellowish too but other than the color fine until the last leaf set or two. The undulata still has its bottom most leaves though too. Now the africana has yellowed leaves too and has lost a few bottom leaves but the leaf loss may be just its growth or a deficiency of some sort. However it us busting out healthy looking leaves at the tip unlike the undulata. Something isn't right I think. I know they are both low light tolerant plants but they have been in my greenhouse since seedlings without issues until the leaf yellowing which has been a while now. The funky leaves on the undulata is fairly new in occurrence. What do you guys think I need to do? Thanks
