Looks to me like she possibly has too much of something though Im sure if you just let her go she has enough green growth left to make it yet :) I have pulled off worse looking plants than this so im sure you can too just keep doing what your doing ill tell you a secret I dont care what any grower says growing seedlings is hard very hard in my opionion Ive been growing almost 7 years and even I can have a dodgy looking seedling now and again somtimes its nothing youve done its just the pheno but most the time it is something you have done lol it takes a highly sklilled and experiecnced grower to keep a plant green all the way through a cycle so dont let it deter you. Your doing great and im sure this plant will suprise you in the coming weeks :) 👊
