I posted this as a follow-up to another thread, but I think it'll get seen more here, and the issues I'm having are really most relevant to this subforum. Apologies for the double-posting of information if you've seen it in S/H.
Backstory: Moved this plant to S/H when I got it on July 11. It had basically no new root growth, but I couldn't tell that for the substrate. It was soaked in kelp extract during root cleaning. Kept it warm and shaded after repotting. Misted it daily to provide an extra shot of humidity. P-bulbs started to shrink a bit, which I expected, but not too bad. Leaves looked good up until July 18, when I left town.
I in a shady place while I was away from July 18-25 because I didn't want it to get too taxed while (hopefully) growing new roots and didn't want the house-sitter to have to make decisions about it. It was warm and humid in the house (we have no AC and it was getting in the 90s that week). When I returned home, I noticed some leaf-tip browning and yellowing. I marked them to see if they're progressing, and some of them are.
I have been watering with either rainwater or DI, and fertilizing at half indicated strength with an orchid fertilizer, so I don't think it's a problem with salt buildup. Plus, I don't see any precipitate on the top LECA.
It's in a sunnier spot since I got home, next to an open window so it's now getting better airflow.
My questions are: 1) should I cut away the bad parts and dust the cuts with cinnamon?
2) Should I get something systemic to treat with?
Any advice is welcome. It also has a new 3 inch flower spike. The pseudobulbs are still slightly wrinkled, which I expected from its shift into S/H, not terribly, so it seems to be ok on getting water. Thanks in advance!
