Thanks! So, this might be a problem of under watering?

could be part of it. How long does your soil take to dry out once it’s completely saturated?

To completely dry, about 2-3 weeks, depends how hot it is.

Ok well I digress. 2-3 weeks is actually quite long to dry out for most plants so it could be that your soil is holding water far too long, depriving roots of much needed airflow, in addition to periods of drying out fully affecting it also. They like to stay consistently moist. Not wet for weeks or completely dry. Have you considered changing soils to something like Al’s 5-1-1 mix? Al is a very knowledgeable bonsai artist member here. Hes helped alot of people w/ plant issues. Thats what mine is planted in, his 5-1-1 mix & when the soil gets dry down to just below barely moist, I water it again until water runs out the drainholes. Al’s soil is loose and mostly bark so it stays damp but has big enough particles to still allow good o2 to roots. info on that 5-1-1 is on here, its an entry in the house plants topic, if you want to read about it. I got my ag as a rescue from Lowe’s, dying w/ yellowed leaves. I repotted it in 5-1-1 & it took off, so I got another rescue & put them together. now its ready to bloom! I wish I had a pic of what it looked like when I got it. Didnt mean for this to sound like an infomercial for Al, LoL- just that so many of my plants thrived once I repotted them into his soil mix. He goes by Tapla on here. Hope this helps!

I do know Al and have learned a lot from his posts :-) I can try mixing the current soil (cactus & succulant mix) w/ perlite, unfortunately don't have bark available. Can this work? That's what I did with most of my plants (about 1:1 cactus & succulant - perlite) and they're doing great.

I did three small plants w/potting soil & about 80% coarse-grade, sifted perlite, all in unglazed terracotta. they dry out about as quick as the 5-1-1 so yes, would work but I would up the perlite content & sift out the dust.

Great! I also just found out 'orchid mix' is almost 100% pine bark (or at least it is where I live) and this mix is super common so I might just get one for the 5/3-1-1 mix. I just watered it (and removed the yellowing leaves) and will keep an eye on how it's doing to decide weather I'll repot it or not :-) Thanks!

Was the brand name called ”Better Gro Orchid Mix”, by chance? Ive seen that at Lowes & the sizes look more comp other orchid mixes Ive seen. I always wondered how well that one would compare. I normally buy bark locally but this year its a bit bigger in size & LOADED w/ sapwood. 😢

Keep us posted on your plant. I hope it straightens out now w/ the repot.

Thanks @Rebecca/N. IN/z6A! No, it's some local brand.

I'm yet to repot but the plant doesn't seem to do so well. Few more leaves have started developing yellowing & one has a really weird yellow "halo". What is this?
