I'm going nuts not knowing where my pH is,
my girls are yellowing from the bottom to mid fans leaves

anyone from around here with a digital pH meter willing to help with testing tap water?

i need to know exactly how much pH down it takes
to bring 20 liter tap water down to 6.5 pH

my tap water are alkaline as much as GHE drops can measure
I'm assuming its over the chart; since it only shows up to 8.5

you Israelis are water specialists, I hear. growing crops with saline water, etc.

have you a government organisation (local even) that will test yr water? comes as a free service in this fair land. then you can work out how much pH down to add.

cheers!

buy a pH meter.

what are you gonna do when you add nutes to the water...

pH meter is number 1 tool for gardeners.. followed by a PPM meter

i just tested i cant say exactly but in somewhere between 7 and 8
7.6 cant be to far off as a starting point; that will tell me where i am now

here it's 7.4 usually,at least in my area

SoG · 07-23-2012, 03:19 PM

can you tell me how many cc pH down used in 20 liter to bring 7.4 down to 6.5?

angeldust30 · 07-23-2012, 07:36 PM

i can tell you how much vineger,i dont use ph down
tell me if that helps u and i'll do the test for you

SoG · 07-23-2012, 08:18 PM

thanks angel, the only common denominator is the pH Down i have!
i found 5% vinegar here, what % do you use?

This is starting to sound like a Snipe hunt. Go to a pet/fish store get a P/H test kit. $5
Propper acid and base to adjust P/H $5

Mix one gallon of nutes and test P/H. Determine how much +\- it requires. (9 drops of acid per gallon for me)

P/H testers are notorious for failing (I've bought four) even if you baby the electrode deionized water can take it out.
