I'm growing in 5 gallon smart pots of super soil, 6 weeks into flower, 3 plants. My 2 bubba kush plants are doing fine, however my og kush is showing a major deficiency with all fan leaves turning yellow and drying up to a crisp, at a pretty quick pace. I'm pretty much left with buds only at this point.
From my research it looks like a magnesium problem? I alternate between 300ppm dechlorinated tap water, and ro water and I don't ph. So I'm not sure if the ph'd water flush method applies to super soil or what I should do? I was thinking of foliar spraying them with Epsom salt and watering with magi-cal today but I'm not quite sure what I should do to save this plant
Here are a couple pictures at the early stages but now it's much worse.
