maybe post some pics and we will have a better idea.
if they are truly sprouts, as in not even a week above ground, i might just start over. it only takes a couple days to germinate a seed and a couple more days for it to sprout but you could let them go and see what they do while new ones are germinating just in case. might find the new sprouts are performing better than the old ones you hurt a little bit.
are you growing in soil or hydro/soilless? ive never needed to ph my soil grows (never done hydro or soilless so cant comment on that lol) but my nutes are also ph buffered.
