well there isnt much you can do about it now besides put them into flower and hope for the best,Im no old pro at hydro but my thoughts are if all looks well then it must be well,I used to grow outdoors for years and the only thing I would check is the ph of the soil and never really used much fertilizer,I mostly would use chicken shit once in a while and I grew some killer plants,so take it as a lesson learned and see how they turn out
