how to safely lower the PH of water?

does anyone know anything i can add to water to get the ph from 7 to like 6.5 or so

can i use lemon juice or something..would that affect the taste of the buds?

Yes lemon juice is fine. No it won't affect bud taste

so..
lemon juice=ok
vinager=not ok

correct?

I've heard its ok to use white vinegar as well. But you have to add it in small amounts. And it may take some time (over night) for you to see changes in pH.

thats wierd. ok thanks ill stick with lemon juice, any limitations to that?

desertflower is correct you can use lemon juice to lower your ph! you can use as much as you need untill your ph is right if it goes down to far you can use bakeing soda to up it! but if you have the money i would spend the extra 10 bucks and buy some ph down from a hydro store or ebay

If you are growing in soil 7 is fine. Don't fuck with it. I learned the hard way on that. I tried white vinegar to lower it from 7 to 6.5 and woke up to 9 out of ten Hindu Kushes dead.

yep! im was telling you how to lower your ph in your resv.
