Absolutely ! I have a runt(GSCE) that was half the size of the rest of the girls for the first 3 weeks. Well now they are 1 week into flower and I can’t tell which one is the runt anymore by looking in there. She matched the size of the rest of them. In alot of my reading I’ve done here I’ve came across many many post that people say their runt produced the best of the bunch. Also they both look healthy to me.
Look a little dry. I personally would ph some plain ol water to 6.2 or so…wetem good…leavem be. No nutes. Givem time and love. Watch light on that shorty. She looks thin on stem and might stretch and fall. Those starter pots act like fabric and will allow roots to fill out well. I used to use them now straight to peat pod and right into final pot when they show green. Just my experiences. Concentrate hard on the strong 1 but dont give up on shorty. She might take off. If not…plant another bean. Patience and basics. Not all will make it so if it dies…the world revolves and try try again. Just my thoughts. Also if fem…same strain…if 1 makes it good…clone her for more plants.
Like kids. One can be real tall and skinny, other can be short and fat. No two plants of the same strain are going to develop the same, unless you’re cloning.
