ph down will only lower your waters ph and not your soils.. What type of growing method are you using
good old sunshine in 20 gallon totes,i added to much lime i think when i transplanted 5-days ago,so 2hrs ago i mixed 1 teaspoon of vinegar-6% acidicy to 2liters of water,and they have perked up already,i see a big diff already,i figured it would take a few days,so vinegar works for soil,right?i did;nt use ph-down my bad...whatcha think bout vinegar 2 go down,baking soda or lime to go up to correct ph issues? Also soil can be forgiving with minor mistakes,i've read that it's more of a shock thing 2 the plant if the ph changes fast,say 6ph in smaller pots then 2 a 7,7.5ph when i transplanted into totes,plants dont like big ph swings like that.i have 2 be more careful,it's hard 2 always do ev-thing rite when ya got 12,3-4ft plants,its a lot of soil 2 mix up transplnating 2 20 gallon totes,i ran out of my cured soil and hadda mix up more and i fucked up i guess by not measuring everything out cuz i was in a hurry.thanx for ur info-so ph up,down from hydro stores only treats ur feeding water,good 2 know.
