My first successful grow so far:
This lady is 7 weeks into flower,
pH runoff has been right at 6.0 UNTIL the past week.
Here’s my confusion as a newbie:
I use pH up in one gallon of RO water, when I test the mix and get it around 10.5 my runoff is 6.0 - 6.1 and she’s looking healthy
(also adding appropriate ILGM nutes)
Now I put pH up in my gallon of RO water, bring it to around 10.8 and my runoff is only 5.8
I’ve looked in the grow Bible, and online and still can’t find the proper way to use pH up.
