My two plants sprouted 4 days ago. They are both in the exact same soil and get the same lighting. The first one is about 2 inches tall and on it's 3rd set of leaves. The second one is still struggling to get its first true leaves going. My problem is that the cotyledon are yellowing but everything as a whole is good. I have been sprinkling a little water every now and then but nothing I didn't do to the other one. Does anyone know why they would be yellowing THIS early. Also, it has taken a couple hits from a lamp and might just need sometime to recover.
