About a couple of weeks ago I picked up these two rescue Phals. from Lowe's. They appeared to be suffering from under-watering. I got them home and watered them well. They're potted in sphagnum moss. The fuschia plant recovered quickly and is still doing well. The the white one which has two spikes and at the time at least 5-7 blooms on each spike, two flowers on each spike are small like those on minis and one of each 2 didn't open fully with the top sepal still folded over like in bud.
This white one however after watering immediately dropped several flowers, except for the small flowers. (I did post about this before when I repotted and found some dirt-like substance that was determined to some extent of have been old medium.) I repotted it with bark/charcoal/lava rock mixture and used some fertilizer. I did some root pruning but the roots seemed alright. In the last 5 days or so a couple of old inflorescences started to yellow and wilt, I cut them off. The leaves have remained limp but the tips of a few of them have started to brown and sunken in. Now I see that all the tips are sunken in like that. And today inspecting the spikes I see "lesions", little vertical tracts and pitted areas that I'm pretty sure weren't there before. I don't see any bugs. Oh when I first noticed the brown tips (Monday) I took the plant out of its pot thinking I have root rot planned to leave out to dry out for a day then repot which I haven't done yet but have spritzed a few times. As you'll see in one of the pictures, there are some white circles on the underside of one of the leaves which I thought a week ago was due to my hard water but now it appears there's more.
SO, any thoughts? Should I cut the browning tips off? Remove the leaf with the white spots? It's in the other room away from the rest of my Orchids, after having had both rescues right next to them for a couple days but also next to the other rescue that's still doing well.
Thanks in advance for any help you may offer.
The second picture by the way is the underside of the leaf if you can't tell.
