I have recently been asked to figure out the Hanna System at work, the two people who took care of the unit left abruptly. I am trying to figure out the Recipes and EC Values for the injection for the fertigator, I have a break down for the old nutrients we used but I need to find one for Athena Pro. I have emailed and called Hanna without response as of yet and well time is of the essence, I’m trying to lower the EC from 3.0 to 0.5 so we can give the ladies a flush. Unfortunately I can lower the EC to that level without a problem, but since the % of mixture from the barrels hasn’t changed my pH value is spiking, went from 5.7 to 6.7. I know that a small spike in pH for the last few weeks isn’t a issue, but want to be able to control the pH and EC for the full growth cycle.
Any one with any knowledge would be super helpful, I have read the instruction manual, but unfortunately I went to school for history not advanced mechanical engineering
Thanks for your help.
