Hard to say as the pics are kinda blurry....
I'll venture this at this point,,,,,add a Cal/Mag? Hard to see, but the brown spots look like Cal problems.
The yellowing lowest leaves are doing a natural thing......It's time for them to go, and the plant is doing it the right way. Consuming the stored nutrition in those leaves.....Remove when green is gone from them...

Yeah,,,MG is a bitch.....Try DynaGro next time.....Works great, 1 thing to use. Oh yeah, get a better soil too.

I don't see any nute burn. Pump up the nutes instead of cutting them off after flush. None of those leaves are curved from pushing nutes too hard. I don't see any cal def. I'd say cal/mag never hurts though especially 1/2 through flower(molasses will do the same almost in a pinch). My buds are bigger when I use cal/mag..... Your not feeding them too much.. I'd say looks good and has promise. Pump a little more juice IMHO.

NOT low N.....IF ANYTHING at this point I would ask what is the NPK ratio of everything your putting in and be looking at what the P value is, along with the K. I'll bet they are both higher then the optimum for Canna......But I already knew that from the use of MG.
Don't start adding nutrition as all your going to do is set the stage for new problems down the road.
Don't flush!!!! You flush toilets, NOT soil.....
As far as that link above goes.....There are a cpl of those pictures that are wrong! NOT to mention that the stupid "chart" in the second post should be deleted and banned! It is confusing and VERY incomplete.

AGAIN<<<<>>>>DO NOT "PUMP" ANY NUTES!!!! your using MG and that's to strong already!
