The 2-in-1 pot is not burned. Done suprisingly well and only showed signs of the top leaves curling recently. My theory is this has something to do with the roots as it has gotten bigger and there is still the stump of the other plant in the pot. Wasn't an issue at 10'...becoming one at 20'? The topped plant is def nute burned. The camera makes it look better than it is and it has looked this way ever since I put those MG nutes on it (first time I nuted)
As far as PH...I dunno...it wasn't an issue until I MG'd it and I haven't been testing it. I use tap water through a PUR filter. I haven't used calmag or epsom, but I switched to Fox Farm Big Bloom (no more MG). Been going low dose and every other watering because of the MG soil. Has not seemed to really further agravate. I think the topped plant is going to be somewhat problematic no matter what. That's the issue with time released soil. You can only do so much and your constantly fighting to correct. Won't buy again. The top growths look ok, so I'm going to keep an eye on it.
The 2-in-1 plant. I'm not sure what to do about this leave curl. As long as I get some yield I don't care, because I will never put 2 plants in one pot again, but I hope the top going foward isn't screwed.
These are 3 weeks into flower. I'm not sure if I'm on average time for bud development or behind? Also I put these things on 12/12 at 9-10" thinking double height plus some fudge factor. In 3 weeks they are 17-19" and I am tying them down! Do you think they will get much taller now that flowering has really begun? I only have about 6" more for them. Def flowering at a lower height next time with LST.
