So just to circle back on this for my own reference and for anyone who is interested - it would appear I went crazy with the roots organic Cal/Mag and that created a P/K lockout. The Malawi was more sensitive than the Dougs Varin and actually first began showing signs of distress weeks before with intense clawing, which may very well have been a reaction to too much N…but I don’t know where that would have come from so I’m still not sure. Could simply be a Malawi sensitivity to N which Ace seeds mentions without much fanfare on their site.
The comments regarding Molasses were super informative but I don’t think I’ll completely drop it from the mix. There are plenty of advocates who use it during flower so I believe there are benefits when used sparingly. It possesses some amount of calcium and the DTE 4-8-4 possesses some amount of Magnesium…so I’m inclined to introduce molasses during flowering (in future runs) and when combined with the 4-8-4 I probably won’t need to bother with the Roots Organics unless a deficiency appears. However, I will make sure to PH my water after the molasses is added
I’m finally measuring PPM after each watering and realizing how useful it is to gauge a plant's health when growing organically (took me long enough ). With physical symptoms being delayed by 2 weeks, it feels like I’m watching a slow motion train wreck when I fuck something up. The PPM on the Doug's Varin and Malawi are still 1500 - 2000 but they’re coming down so all is not lost. The Malawi is a beast so I would not be surprised if she still pulls through a decent harvest despite the abuse…then again, I would not be surprised if I fuck something else up before then.
I appreciate all the help from those that took the time to help
