Проблема PH

Hasiklis420started grow question 6y ago

Hi everyone. ☮️ This is my first experience with hydroponics and I just can't stabilize the pH, it keeps jumping around. I lower it to 5.5 and the next day it's 6.2-6.4. What do you recommend? Thanks in advance.

At low concentrations, it's very difficult to stabilize pH. Although I thought that pH was perfect for this. A large amount of bicarbonates in the water will also hinder lowering the pH to sufficiently low values. There are two solutions here: either water treatment or water analysis and taking these values into account when mixing the nutrient solution.

buffer the solution ph with both ph up and ph down, that way it will be more stable. Those jumps happen when the reservoir is too small, so try to increase its size

Lower lighting at switch to 12/12?Do you typically want to lower your lighting when you switch to 12/12? I'm a little confused about what is meant when they say to have a 12" light distance for flowering and 18" for veg. Does that mean lower to 12" at the switch to 12/12, or just maintain a min 12" distance?
