Do tell how you know what the color is supposed to be using something like gh flora series and ph drops if its not too difficult. Even if you were able to do it once it would change over the course of a grow unless you run the same nutes at the same ppm the entire grow wouldn't it? The guy who bumped the thread gave good advice about guessing ph with drops and no meter in hydroponics. It'd take a fool or a newb to try and guess what color pink and green would make for ph to be in the correct range.I am curious because I have never done it, but I imagine that once you do it once you can remember the color. Shouldn't be too difficult.
Did you read the thread before before replying?It would take some skill and experience.
Literally the first sentence.I am trying my first hydro system, dwc.
Maybe I could maybe I couldn't. I don't know because wouldn'tJust because you don’t believe you are capable of doing it
Where did the op say he could? He only had four posts in the thread.why would you doubt a person who says they can?
He didn't sound so sure to me.Can I test my ph even if my water is kinda pink from nutes?
