Gonna transplant seedlings mixed ocean forest and other soil in photo and should imix with organic red white stripe bag also and top soil and main question what strain are they and why they have one leave some of ‘‘em and look like that
Any pot does that they buildup roots before foliage does
Root bound is extremely rare in a well designed setup
Low lighting can cause slow growth
And stop taking them out of the cup
Exposing roots to light can also slow growth
BTW
In case i missed out on it
WELCOME TO RIU
