Looking nice and healthy. But they are going to get crowded soon, are you planning on giving them a little more space? I'm sure they would love you for it if you can, if not, make sure to get them lots of fresh air and keep on eye on the humidity, etc. that's a lot of plants jammed into a small spot, but that's cool really. I like seeing an over-full room way better than seeing a room with a ton of light and a couple small plants, for some reason that really drives me nuts. Something about all those wasted photons grinds me, you won't have that problem. But if you can spread them out as much as possible while keeping them as close to the lights, with lot's of air circulation it will help.
I'm sure you must have read a lot or watched a lot of video's so you must know most of that but since you said you were a noob I thought I'd suggest. They are looking very healthy, good job so far. Looks like you are training them too, that's good. Good luck.
