well i tested the pH and it was 5.0! im absolutely confused cos my plant pots pH dropped to 6.0 so i added water and fertalizer that was 7.0/7.5 (and i havent change the formula since then: 3.75ml BioGrow per Litre of tap water).. so i thought that would bring it up and keep it up?

anyways its 5.0, do i add pH Up to my water and fertz til it has a pH equally opposite on the pH scale, which is 9.5 to balance it out?

the plants look good, nice shade of green.. but the droopage is really bad, they were heavily watered this mornin too and still got a droop on now

heres a pic of one of em but theyre all very uniform in appearance:
