MAC1 Floraflex

I'm using RO water, adding calmagic to around 300-400 ppm then adding v1 and v2 around 30% strength, ph up 5ml at a time intim ph is 6.0. I make up 20 gallons and pushed through the media to fully saturate. Then make another 20 for the week. At this stage I am watering for 3 min after lights on. Allowing it to dry a bit each day to hurry roots along.
