How are they looking?

Some plants are slower than others, but it's difficult to tell if it's the genetics or if you did something slightly different to cause it to stall a bit. What I would advise is that if you need to put a stake in to support the seedling, put it as far away from the stem as you can. All the roots radiate from the tap root and sticking a thickish stick like that right down the stem, you have damaged any roots on that side of the plant and only given it a harder time.

mostly looking fine. best to take photos with white light if your grow lights are colored. very yellow washed in these pics. Normally I see the old bluepurple ones washing everything out. Not all seeds will grow the same even from the same pack or plant, they are sisters of each other. To me they are looking good from what I can see. Some a strecthcing a bit more. Just give them love. and be prepaired, not all plants make it.
