Long story short (not really) the binata was one of the most vigorous growers before I moved back to school. After that the newest leaves just halted growing and I figured it was just stressed (temps spiked to 90F+ and it was a bumpy ride) so I trimmed them off and assumed it would bounce back with more stable conditions.
The last week or so my terrarium has had some big dips in temp at night, bigger than I would like. Everything except the binata though is still doing well. Still no new growth at all and I am wondering if the huge temp fluctuations were the issue since nothing else has changed. The "newest" leaves still are producing dew. Odd though since the pure tropicals and sub tropicals are still growing strong.
I tried getting a decent pic of where the growth point should be. I'm not exactly sure what a dormant binata is supposed to look like...
Doesn't look too good. There also seems to be some fungal growth on the media as well as some algae. Do I have a combination of problems here? What should be done to get these guys back on track? Or should I just let them do their thing?
Temps are going to be more stable, hopefully, now that the heat is kicking in at night. I expected more of a die off from the top if it is going dormant but again the leaves are doing well in terms of dew and the worse part is closest to the media. Is a complete media change in order to get rid of the junk growing on top or should I start using a fungicide or let the pot dry out more?
Sorry for sounding so desperate and being long winded. I'm just flustered as to what the main problem here is and why the binata is the plant taking the brunt of this. It was doing so well right after I received it (and it wasn't exactly in the best condition after shipping) so I want to get it back to normal.
