Phosphorus? Potassium? CalMag? What is going on here?
So in week 8 after flushing with EC 0.4 and giving extra PK 13/14 afterwards (EC 1.9) there are still problems occurring. I personally think it’s a deficiency of potassium and phosphorus. Can anybody give me some advice or tell me how to fix it? Thanks!

Deficiency ? Chlorine from tape water ?
Spots appeared after last watering, 4 days ago. It doesn't seems to evolve to more spots. Using basic gardening soil. Chlorine in tape water X 4 those days, because of covid-19. So if not a deficiency, might be Chlorine ? Or Chlorine killing life on the soil? Suggestions ? Help!

Magnesium deficiency? How to cure it?
Is this a sign of magnesium deficiency (my other plant has similar spots)? If so, I've read online (on the Canna nutes website) that I should spray the leaves with Epsom Salt (2% solution): is this correct? Any other suggestions? Thanks in advance

I have symptoms of both N deficiency AND toxicity. Paleness is spreading up from the lower leaves, but there's also downward clawing & "burnt" tips on other leaves. Plus some weird brown ends on the larger fans. Haven't fed any bottled nutes. Halp?
