i just pulled the seed casing off of my inch and a half long plant.. 2 of them were yellowee. is this due to heat stress, or iis this normal and they should green up once the light gets to them?
I've had seeds do that, sometimes the cotyledons stay yellow, sometimes they turn green. You should be fine. With my seedlings i usually jst put them under a CFL to veg untill i feel like moving them. Peace!
