Durban Poison Dutch Passion Photoperiod

Week 7 of veg. I'm away this week so the Blumat setup is in full effect. I filled it with 11g, with 3.75mg pre gallon of Maxibloom and with a bit of either magnesium or calcium deficiency showing on the lowers of one of the plants, I've started to add Ca/Mg to the feed at a rate of 1 tsp per gallon. I've also mixed up a foliar spray with it as well and I'm spraying twice a week. I've also moved the light scheme to 12/12 to trigger flowering..I know that they're low (as intended) but I expect a lot of vertical growth in the next two weeks, so now is go-time.
