This looks fine. Top that in 3 more nodes.
Makes me chuckle everytime I read a post of someone freaking out over the condition of a plant with 4 leaves. It is definitely not just you either. Haha, for real, if a seedling ends up coming up yellowed or looking pitiful you should rogue/cull/eliminate that plant as it is a waste of time from the get-go.
Plant and clone many, and kill off many more. Breed the strongest plants you can that can endure the greatest amount of abuse. Do not cultivate the weak or you breed the weak. Do not be afraid to rip one out and throw another in its place. If you need seeds, get some dank weed you like and hope you get one. From that, grow a plant and stress it the hell out so it'll be bountiful with progeny. Then, refer to the advice above. Plant many, kill off many more.
