What lighting are they under?
some run of the mill LED strips, full spectrum. I put my expensive light in flower room

What lighting are they under?
For the last 6 months
my tap water has come out at 7.2 and I need to add 3ml+ of PHdown to my 4 gallons of
water to bring the PH down to 5.8. I always check with the drops to make sure.
I think 2 gr per gallon or about 150-200 ppms for a foliar spray.

I applied the foliage spray. Is this a one time thing? Or a daily thing? In the case that it is Mag deficiency, how long until I should start to notice?
Cool, I only asked because intense LEDs too close can cause all sorts of problems that present themselves as various other issues and can have folk running round thinking they have any and all deficiencies.
I doubt that's the case having seen your lighting unless your running shit loads real close.
Looking at the canna chart it looks like your feeding 100%, I would cut nutrients down to 2 thirds strength.
I would treble check ph with a different test kit or pen and make sure your root zones not cold (like say a tiled or concrete floor)
I have grown with canna line for years and never had a plant look like that.
should notice in a day or two and its not a one time thing every few days at a low ppm. at least three times is what I recommend and then re-evaluate what it looks like as far as the foliar feeding is going. or if you added a little mag at the roots then do it at least two times then re-evaluate.
thinks its a cross between k and mag deficient.
