Seedling responded greatly! How do I keep her healthy at this point?

I posted a few days ago in regards to my young seedling. She was droopy, yellow, purple, and I knew something was up. She has really perked up for the better and started to grow again. My led was 15 inches away... way too close. I moved the light up to 24 inches. I had not fed any nutes “this is a coco grow” so I gave her a really light feeding of micro, bloom, and cal mag. Finally I just let her sit for a few days. The first and second day there was almost no response, then I woke up this morning and she was not drooping, and her new growth had gained size! I am proud of myself, but I want to keep this on track. I am reluctant to feed again until her coco is a little less damp. Is this correct? Should I let it dry out some? Also when she is ready to feed again how much should I do? Im using GH micro, bloom and cal mag. The first pic attached was her a few days ago. The second one is her today.

Don’t over water at that stage I would be given her a light spray once or twice a day

wait till about 2 waterings then give her a TINY dose of veg only. do that about every 3 waterings, letting her dry out before watering. soon she will be big enough to acually feed but for now she does not need much if any.
