so this is the start of my second grow (first grow currently in flowering). I planted two seeds which I plan to move to a greenhouse once the weather is nice enough. Anyway, one of the seeds (which is Northern Lights) appears to no longer be a viable seedling but just making sure before I toss it and plant another. It only has one cotyledon because the other one got stuck in the shell and then detached from the stem as the plant was starting to sprout apparently. here is a pic: The other seed (Blueberry) is doing fine though and I have some spare seeds so it's okay. Here's the blueberry seedling:
Grow it out and see how it looks, you have 2 seeds at the same age so you can see if the one cotelydon is gunna slow it down or not
