Hi I'm growing DTW in coco and I have a 60L nutrient tank, but I am having problems with the PH dropping to 4.5 after around a week.
I fill the tank with plain water with a pump in the bottom and leave it for 24+ hours.
I then mix up the nutes (currently using shogun) so the EC is where I want it and leave for a few hours until fully mixed.
I then set the PH to 5.8, the PH will stay around 5.8 for about a week and then when I go to feed the girls one evening it will read 4.5.
I have a high end EC and PH meter which is fully calibrated and has been checked against other meters.
My water comes out the tap at under 0.4 EC.
The nutrient tank has a mj1000 pump keeping everything mixed.
There is no wild temp swings where the tank is located, it sits around 18-19 degrees C.
Any help would be appreciated.
