Hi everyone. I have a question about my gigantea alba. I have only watered it once in my care since I've had it (which is about a month). It's in 100% moss, which is what is what it came to me in. My problem/question is this. I feel like I should be fertilizing it. However, with the moss retaining so much water for so long, I'm on track to water/fertilize once a month, if that. It's currently growing a new leaf and making good progress. There is new root growth in the pot. BUT, the grower pot is also growing green moss as well impeding my ability to see the roots somewhat. I also feel like the current moss is degrading.
I know gigantea don't like to be repotted unless absolutely necessary. Do you think I should repot while there is new root growth so that I'm able to adequately water and fertilize and get fresh medium in the pot? Or should I hold off? Thanks for any advice.

ETA; picture was taken right after I watered it; the moss is freshly wet.
