easy on the Ca-Mg, remember, those are not primary nutes but secondary in terms of amount needed, and too much will fuck up other things! just stay with the usual dosing,..
I see mainly P defc. which is badly affected by the cold, but others as well especially micronutes which you may be getting defc.'s of now too (affects the tops first and worst),..... you have lost ground here, and only so much can be done to catch up,.. consider using a a stronger bloom booster, high P-K, synthetic is best for rapid uptake,.. don't sweat the use of this with "organics", it won't hurt anything of screw with the quality,... I use a combo of both usually,... keep in mind the plant doesn't care where the nutes came from, they absorb them in only very specific forms, organic or not, it's all the same to them,...i.e., nitrate is nitrate regardless,.... best check you soil pH, in-pot as well, despite the ill-advised idea that organics need no pH monitoring, it's pure BS,.... no need to pH adjust the solution usually is what that gets confused with I believe,... The Accurate 8 soil pH probe is a good unit!
