Once again, thank you.
Curious though, the leaves turning to strings are on the older prons, the leave second from the bottom of the spred - and on both sides - matching. This doesn't seem about left over tissue but it folding back up.
Additionally, I get a fare amount of sun throughout the day but that window is s s/w facing window and has risk of direct sun (if I forget to pull the blinds down). The center of my flat has great sun, especially in the morning (east facing) - nothing direct but my bedroom get the most sun as its west facing.
How much indirect sun do these guys like? If I put him in the bedroom there is a great spot, fully lit but nothing direct.
Soil is a mulch feel with pieces tiny broken up wood? it is a loose feel, not a flower pot soil if I can describe.
I also noticed the new leaf at the bottom has gone brown at the top and dried up, half.
