boo! I'm glad you have more seeds. No big deal, part of the learning curve and you weren't too far in.User error,feel so awful my first batch got fried because of way low humidity in 28 to 35 the lights being strong they got necrotic. I've never seen it before, inside problem. So got humidifier and have second batch Started.
This! you probably wanna keep those lights at its lowest setting and far from the tops until they are established.Keep those lights turned down might help too. HLG brings the fire!
