"Optimal nutrient absorption varies for each major nutrient that cannabis plants require. The optimal pH for absorption is much more variable in hydroponics than it is in soil. If you allow for a range between 5.5 to 6.5 instead of always adjusting to the exact same number, you will allow for greater absorption across the board."
"Make a mix in a separate container first then add that to your reservoir so that changes take place slowly. Remember that pH drift is not only normal, itβs desirable. Allow the pH in your reservoir to change gradually, but make sure you keep within the range of 5.5 to 6.5."
Don't target 5.8... You'll have much more success if you let the ph swing..
"I am of the studied opinion, full pH swing grown cannabis is vastly superior in quality to steady pH (buffered) grown cannabis. In my experience the last decade, high transpiration, a full and healthy pH swing in the root zone and a balanced nutrient profile are integrated keys to growing low nutrient strength, superior quality cannabis. My goal is to share the insights I've gained, so your hydro experience is both simplified and extraordinary. I urge anyone interested in growing a higher quality of cannabis to read it completely."
