Hey everyone i hace a question about growing hydro. I know ph changes but mine always seams to drop never goes up. Is this a normal thing.
It could be a number of things, dirty rez, pump , or dirty tubing, bacteria in rez, also the way u mix ur nutrients etc. What do u ph at? Ph also goes up during the day and down during the morning so depending on when u check it that may be another reason. Most ppl I know who had the problem took everything apart and thoroughly cleaned their system. Most ppl use hydrogen peroxide to help aid roots/water just depends on what ur plants look like. I’m not a hydro grower anymore but I did do some research when I had my grobo. Hope I could help maybe someone with more hydro knowledge can be of help. The only thing is it’s a ghost town in here now!
