It looks helthy , slow growth maybe? I'm no pro or anything but the pants that I started 13days ago are already working on there third set of true leaves and what not, and that's just in rock wool, under two floresent lights
What kind of dirt is that ?
And what lights are you using
Also what's your water like ?
Also is that a clear jar your growing in?
I've hurd clear is bad because it exposed roots to light, don't know for sure also what about drainage
Other then that I'd say they look healthy, when did they sprout
Ps once those embrotic leafs drop alittle is burry that stem up to close to the top of the glass
