Durban Poison Dutch Passion Photoperiod

Week 13...missed updating week 12, but that was because I was out of town. Still running blumats and I've been further fussing with them. I've had a few short runaways, nothing disastrous but a bit of a pain. I've started to use Drip-Clean in my feed water and it's been a good move. I also dialed back my drip so the plants are getting less water, which seems counter intuitive, but also is working. Of course, you can see that the lowers look terrible. Calcium deficiency early moved on to a magnesium issue. I've gone to using filtered water with the Maxibloom, plus 1g per gallon epsom salts and 2.5ml of Ca/Mg per the Maxi schedule. I've dropped the feed down to 2.5g per gallon from ~3.5... I'm having a hard time adjusting to the Blumats and feed strength...but that's also probably compounded by the fact that the Durban is close to pure sativa and I just realized that it probably doesn't want as much fed to it. We'll see how it goes. I think the worst of the worst is over and what of the lowers didn't already fail will slowly fade out. Though the bud leaves are fine minus a bit of burn and show no signs of fading. One plant is ripening a bit quicker (The lower plant) and the taller one is still mostly white pistils, etc.
