Are my babies doing ok

so here is the 5th plan t don't really know if there is really anything wrong with this plant besides the drainage for the soil so i over watered in the beggining and then it had nitrogen toxicity i believe so flushed and it has been doing 100x better same for this last plant here are some pics so that's it for the big update lol only took 3 post but please let me know whats y'all think pros and cons advice and criticism thanks
