Nice…
The long one… Looks like it stretched… You may want to check your lights… There is a thread about DLI… Daily Light Integral(?)…Photon App for iOs and Android…
The ones in the rooter cubes… My fear would that they might dry out too much sitting on top of the soil like that.
Do you have fans blowing air around… The little slightly “dancing” plants use the movement to strengthen… Like trees in the wind. That may be another reason your long one isn’t standing up… You may want to support it or add more soil to stabilize it.
Please remind me… What’s your light?
