Question on ph

How important is ph to soil and water when growing. My soil ph of scotts potting soil seems to be at 7, while the water i use is 7.15. my girls seem to be doing fine. will there be nutrient lock or no? is vinegar a recommended and safe way to bring it down or should you even bother and just let er' grow?

im in same boat as you... bought litmus strips but theyre useless all i could get was red and blue ones
i wanted the fuckers you got at high school theyd b ideal

ph as to all the medium needs are a must try to stay around 5.5 6.5 in the ph.
test ph before u ad feed and after as most nuts depends wat u use will raise ph get things right.
everything is a must on good end product for taste and quantity why skip this and that and get 1 oz when u could add a bit of this bit of that and get 3 oz off 1 plant
vinegar not my choice u can buy ph up ph down from grow shops dont cost much the strips are ok to use i compared them to a ph meter and they are pretty good

5.5-6.5 for hydro 6.5-7.5 for soil.it is very important to keep you soil/water within the proper range for the growing system you are using.if you do not keep your ph within proper range your plant will be unable to take up important nutrients and will cause damage to your loved ones

so you're saying my soil and water are fine if they are around neutral (7) then? cool!
