An hour after lights on, when they're awake . . . .wanna see if there is any clawing on her sugar leaves . . . .
Quality, sound as, with 9.0 tap, you ain't gonna be needing PH up . . . lol
Bleeeugh, ok so we'll get a general (lol) idea of the ph . . . . I guess the wife would literally hang you if you bought a Bluelab PH meter at 80+ bucks
Ok so;
a reading from a gallon of nutrient, that has had its water PHd to 6.0 like you normally do.
a reading from your new 5 gal feed that has not had it's base water PHd at all
We need to know the difference between what it's been having and what it's goonna be getting, if it's more than 500 to 800 times difference (0.5 to 0.8PH) then we need to slide in the new regime gently with 0.3 to 0.5ph increments, including , obviously, the waterings/light feeds inbetween . . . .
Hear from you in a bit m man
