Why is this deficiency or toxicity spreading so fast!?
Had a light case of what was believed to be calcium deficiency. Ph, EC and ppm all seemed normal for run off and I've halved my nutes but kept a higher dose of CalMag going. Didn't water them last night now it looks even worse, what should I do and will the end product be ruined?

White leaf tips and spots? Help :(
Im using spring water from a mountain near by,but it is pretty acid (~4.8 ph). Could that be the reason my plants have white tips and a spot on the leaf? Or could it be the height of the light? I will raise the ph to about 5.5-6.2 ,so hope for better results. Thank you :)

K deficiency?
in the last pictures you can see what to me look like an early deficiency of K. Since she is in the first stages of flowering I would say that's the case, reading the literature online i noticed a lot of similarities, what do you think?

Should I check only EC or PH is also important?
I was told not to check for PH, add the nutes and check the EC, reach the level I want and that's it, is it right? I'm also checking the water coming out of the plants, they have EC 1+ above what I gave them. If I gave 1.5EC then it will have 2.5EC in the water coming out.

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

Discoloration on leaves. Why?
I was looking at a closeup view of an overhead pic I took yesterday and noticed some slight tan/bron color along the sides of the 2 bigger leaves. I'm wondering why. Nutrient burn? Sulphur deficiency? Something else? Any thoughts?

Nute burn or deficiencies?
Can anyone give me a clue as to why the leaves on my fast eddy are going this colour, she’s fed every 2 days with tri part nutes. At 1/2 the recommended dosage. Guessing she’s got about 2 weeks until I start to flush her. Thanks
