Day 13 Auto from seed. Feeling small, or maybe I'm just impatient. Help me decide.

Here's a photo. First grow, in case it wasn't obvious. I know Autoflowers start off a little small but this seems too small, especially the stunted one on the back right.

I'm following this Growweedeasy guide to a T, except I have a VIPARSPECTRA 600W (250w actual) LED light. It's currently running 18/6 at a little less than 2 feet from the plants. Medium is coco and following this nute schedule (PDF) and regulating PH before each watering. Temps in the low 70s, RH in the low 50s.

Be more patient or do I need to switch something up?

Be more patient - little plants are filling their roots into their pots.

Hello and welcome to the grow forum GWE Is that straight coco in the pots? I run Vipars i keep the seedlings 30" or more but your instructions may differ? Yes the first 2wks are slow then seems like they take off if all is correct with the environment.

For Day 12, they way to small, easy to stunt babies from to much water, which is my guess Whats been happening.
Young plants can't stand to much water, they need oxygen.
On my seedlings all i use is a couple of spoonfuls of water, just to keep damp.
12day autos, should be larger, don't use much water,

They look small yes, but a good thing is they are still "healthy" (Not wilting). Just keep up eith them and don't over water. Someone told me on here that sometimes too much attention is a bad thing, so keep an eye out just not too close.

Thanks for the feedback y'all. I added some perlite to the coco and I do think overwatering is the issue here. The plants have already rooted out of the rooter I started them in, and the coco was still very damp below the first inch or two. I'm going to let them dry out a bit before adding any more water and hope for the best.
