Seedling

It looks like shit. Just kidding. It looks just fine and I’m sure you already know that. Not like it’s the first .. or second you’ve sprouted

Its pointless to ask these Questions mate.. All seedlings are just growing with what's on top and by RH. Unless there was a mutationed leaf etc. Then, until you are 2-3 weeks in you'll know if its stunted etc. At this stage. They all look de same.. Idk if that's an auto or fem But your cup, they aren't the best to start seeds in. Your pot should have holes at the end. In doing so. It cause air movement to go through the substrate. Also on holes. Make sure to have 1 in the bottom to let any overflow out. As at this young, she'll drink lil. So u don't want water in the bottom They are good for seamless transplantation though. You just slice the bottom off at the base wit a blade and then a slice along the side. Put in pot, cover with soil & then pull up. Just keep a high RH, anything 60+ is ok. 70 is optimal but I see you've other grows going. So, 60% with good airflow in your tent will be good for old & new crops. Not optimal but, still good for various stages of plants in 1 crop.

She looks fantastic🙏relax and good luck!

Yeah man she looks fine. Much better than my Janky Jackie diary. Just a bit of patience and let her grow.
