I have some Afghan in solo cups filled with FFOF & it looks healthy to me; however, it's 2 most bottom leaves are yellowing & looking like they will fall off some time.
Could this be a nitrogen deficiency, despite them constantly praying & not really looking pale. I thought FFOF was more than enough nutes (maybe even too much) for young plants in solo cups?
