Hey yall,
Thanks for reading this, up until this week everything was going great but recently I have been losing leaves on my plants, salvia, chacruna, and b. Caapi.
The room humidity reads 66 and 70 degrees and they sit under a nice window underneath the porch. Any help or reccomendations would be greatly appreciated.

To provide more information I water about once a week, use a ph of 5.9, they are in a mix of coco, cactus soil, and perlite for more drainage. The salvia and psychotria have lost quite a few of the lower leafs and the b. Cappi cuttings dont seem far from losing all of the leaves they have put out so far.
 
How does the soil typically feel before you water? When you lift the pots do they feel bottom heavy? Are they getting direct light in the windowsill, and are you adding anything to the water to change the pH?

Without much to go off my guess would be an issue with over-watering or too much direct light, as both plants prefer shade. And unless your tap water is especially wacky I wouldn't worry about pH. Plants have evolved to regulate the pH of the soil directly around their roots so they can selectively take up the nutrients they need most; so given that you're working with decent soil and relatively neutral water, messing around with the pH too much can inadvertently cause all kinds of other issues.
 
They have been moved back to the humidity tent they are in a southern facing indoor greenhouse with 60% shade cloth. As far as the pots the psychotria feels pretty light whereas the salvia and b caapi are mildly heavy. Just watered the psychotria by misting the soils for about a minute till the pot was heavy but no water was coming out the bottom.
 
Sounds like you've got a decent handle on it.

My only suggestions really would be to make sure you're giving the plants ample time to take up water already in the soil before watering again. Obviously don't let the pots totally dry up but try to be aware of moisture that may be accumulating at the bottom even if the top feels dry. I find lifting each pot every day (even on days you don't water at all) is helpful for gauging how much they're actually taking on, and you can use visual cues from the plant to tell when they're thirsty and then take note of what the pot feels like.

I'd also hold off on adding anything to the water or soil to adjust pH.

And as a last minute thought, they could just be hungry - which would explain the yellowing. Maybe try topdressing with some quality compost or worm castings. If you have fertilizer handy you could try feeding at a low dilution to see how they respond but I'd personally recommend trying something like worm castings before a fertilizer.
