Just check your ph after you mix your nutes, when you add ph up or down, do so in small amounts to avoid pH swing, and mix the solution thoroughly for 10-30 minutes depending on how large your res is.
be sure to check your nutes at least once per day, also be sure to check ppm levels as your nutrient strength will rise over time due to environmental factors.
GanjaRobPDX Reviewed by GanjaRobPDX on . pH when to check? Hello! I am growing hydroponically in a 5 gallon bucket with a rockwool cube. Also using Fox Farm Hydroponic nutes. I have a hannah ph/ec reader. My question is when do I check the ph? I change the solution once a week. Do I check it right after changing the solution? Do I wait a day? I'm barely getting my calibration stuff this week so I'll FINALLY get to start using my meter! I just wanna make sure I do it correct the first time.:thumbsup: Rating: 5
