F.. . ..
Soaking those pots each and every time you water, wet enough to where it's running down the outside to the pots and giving you at least 20% runoff. You may be getting good run off but not soaking the pots and you really need to soak those pots.
With no background EC to deal with in my grow room, I would be feeding four mil grow two mil micro and one mil bloom per gallon of water. I probably wouldn't do more than half mil calcium at this stage of growth. you may live somewhere where that feed will put you over your total EC and you'll have to make adjustments.
I would not go below 5.8 pH at any time, and I would put the upper limit of drift at right around 6.2 to 6.3. stay in those ranges and let them drift back and forth and you'll be fine. You would be absolutely amazed at how much 0.3 change in pH can affect nutrient uptake especially when you go below 5.8 you start missing a lot of calcium.
