30 people say watch your PH, one person say's its bullshit lol, sorry Ninja! Stick with the proven methods of growing Sukalas. Not having a clue as to whats wrong with your plants I do know that they are now a lost cause and will probably not amount to much so start over, it'll be sad but quicker IMO
! I would also not be to quick to blame the nutes as much as the proper amounts, as Ninja says get a meter, you need it! I have used a few different nutes and have not found a big difference in quality (plant growth) but have not found one that kills the plant either
. You need to start again, keep res temps down, feed at the recommended doasges, keep ph in the recommended (by the masses lol) range, and you should be ok. I just started hydro as well and have done rather well by following those rules, at least I try to follow them, not with out a couple af screwups lol.
