well, I have 1 remaining female plant from my 4. 2 were male 1 was hermie. I decided to buy a pH tester today for water, and found the pH of the water i was using was 7.9. I know cannabis prefers a pH around 6.8

does anyone think this was slowing the growth of my plants?
im at 2 weeks flower, so i have a ways to go before harvest.
also, i wanted to see something, sorta like an experiment.
i ran my tap water (which i was using for watering) through a PUR water filter pitcher.
this changed the pH from 7.9 to 6.7

im going to be using filtered tap water from now on.
just thought this may be helpful.

anyones 2 cents is appreciated.

thanks.

the actuall prefered range is 5.8-6.2* but you can use a couple drops of fresh lemon juice, or vinegar to lower the ph.. but notice that the vinegar should be new, cause after a while of storage, vinegar starts to ferment into something that can be harmful if not fatal to your plants.. so try a new bottle.. a couple drops until it reads just about 6.0* that should work quite well & trust me, theyll love youu for it!

The lemon juice should be fine . i had that same problem on my first grow . Now i use ro water . My tap has a strong buffer in it very hard to lower the ph so I buy ro and it ph's down easy with lemon juice.

thanks again. me being a cheap ass and not wanting to buy water when i have it from the tap is my main problem. haha. but i think ill be alright. now that i have this tester, ill be able to know if the pH is off, therefore i wont harm the plant with unbalanced water.

Did you test the run off with the pH tester? Was the plant growing funky or anything like that?

no i didnt test the runoff. plant seemed to be growing fine the whole way through. it might have been slowed or stunted for some time but besides that it was doing fine.
