Ive been using about a TBS of White distilled Vinegar as a PH down and its brings the PH down by 1 point. It works fine for my older plants that are flowering at the moment but it seems to be harming my youngins that are about 2 weeks old Is this a bad thing to use as a PH down?
yes, i've tried a plate of vinegar to help rid the smell as i've herd and it killed the lower leaf sets.
