Advice on Zygolum Louisendorf repot

[Gepwin]

I have a few questions as a new grower so I’ll try to be as organized as I can here.

The first orchid I got was this Zygolum Louisendorf Rhein Moonlight that I have had since November. It arrived potted in moss. Not having any experience, I wasn’t sure if it needed repotting when it arrived but I am now worried that the moss may be old and breaking down. Also the pseudobulbs have begun to wrinkle a little, I don’t know if that is normal for this plant or if it’s a sign of dehydrating. If it is, I think I am keeping it moist enough so that would mean something else might be wrong.

I am nervous to repot even though I know I will need to sooner or later, but now the Zygo has been growing for a few weeks so it seems like it’s time to repot if I’m going to.
I have seen a few things that I don’t know if I should be concerned about regarding repotting. For instance there is a spot that showed up a few days ago on the new leaf growth. I know zygos are famous for their spotty leaves, but this one looks different from the ones it already has and may be related to a slight sunburn (I am now giving it less sun), in addition to it being on the new leaf. I don’t know if this is something to be concerned about, and if so whether taking care of it would add too much additional stress if I need to repot as well.

There also is what may be a flower spike stating in the new leaves and I don’t know if that should influence my potting decision.

Finally on medium. The plant seems to have been happy with its moss so far, so my first thought would be to use moss again but I have also learned recently that the zygo may have problems when we hit summer here. When I got it I thought that I was getting a good easy intermediate temp grower, but since then I have seen several people mention that it needs some cooler conditions than I may have soon. Here in the Brooklyn apartment winter has been mostly between 60F and 80F but I know that in summer it can be hard to keep the temp much below 85F some weeks. Given that, I was wondering if this may be a good candidate for semi-hydro as the evaporation may help keep it a little cooler.

Thanks for any advice, and also sorry for the long post.
