"Loved them too much" just give them water for a week or so. They are young and should not need anything right now. I had to give my2cents

I’m just trying to distinguish if it’s nitrogen or calcium. The cal mag product I use has nitrogen in it. I didn’t want to add more if that’s the problem. I will be just watering until the problem is more obvious... I’ve just never had this type of browning before. I’ve just had burning around the tips from hot soil. Never spots. At the same time I always grew outdoors, so I wasn’t constantly looking at my plants daily.

pics in natural light would help, but...i'd say you do have a slight calcium deficiency, as well as maybe spider mites.
the coco you added to your soil may be sucking up some of your calcium, i think a good dose of cal mag to start with, then a small dose weekly ought to stop the spotting. also it seems like you may be slightly overfeeding, you put a good amount of stuff in your soil, then you fed them twice in a row on top of that.
i say spider mites because some of your leaves seem to have damage that's consistent with mites, but its hard to say in that light

Ok that’s what I was thinking from what I’ve read. Calcium seems more obvious because of the coco. I usually use coco loco which is treated, so I didn’t put much thought into it. It may seem like I’m feeding too much (maybe I am) but I added amendments at very low levels to the soil. The first tea was very weak. The second one could’ve of been a little hot, but the plant was liking it until I noticed this... I do believe it’s calcium though. I’ll get better pictures today

There are absolutely no spider mites though.

you're watering way too often, unless you have them in straight perlite. let them get nice and dry between waterings, keeping them too wet is bad for your roots, stunts them, and it locks out a lot of nutrients, which i think is whats happened to your plant.
if you're feeding them that every time you water, that's way too much.
bump that up to about 450 ppm, feed them that once a week, then give them ph'ed water in between.
or, cut it down to about 200 ppm and alternate feed and ph'ed water

They are in rockwool cubes and it's drying out almost every 24 hours. So
