Halb gelb, halb grün
My plant is currently showing slight potassium deficiency. But somehow only on one half of the plant. The other half looks well-fed. Can someone explain this to me? Like, why doesn't the deficiency affect the entire plant?

How to differentiate Calcium from Manganese deficiency?
They look the same, so is there other criteria to differentiate a calcium from a manganese (not magnesium) deficiency?

Magnesium
I am a bit worried about the early oranging of the flower pistols, I have adjusted cal mag should I continue as normal and put progression down to pre existing deficiency now showing down the road? Certain branches/budsites showing amber pistols in first couple of weeks of flower

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

Yellowish spots ? Magnesium Deficiency ?
I noticed that on some leaves (not the new ones) there were 2-3 yellowish spots. And on a large leave, a point that turns brown. I thought about a small deficiency in Magnesium?

I keep loosing leaves to some sort of nasty necrosis. It affects leaves at all levels, small and big randomly. I had to remove a lot of dying foliage
At first it looks like a asymmetrical spot of leaf starting to thin out to lighter color then tissue dries and turn black. I have high runoff EC3.3 and I blame Easy boost pellets because I only add rootjuice 1ml/L and sugar royal 0.5ml/L to my water. What is it and how I fix it?

Zinc deficiency?
My plant's top leaves appear thin and pale. My ideas are iron deficiency or zinc deficiency. I'm using RO water. The plant was recently aggressively trimmed of course. Should i flush with non-RO water to increase the zinc?

Rust spots
My lower leaves are showing rust spots along the veins. Appears to be a magnesium deficiency but I am feeding cal/mag. I also growing in ocean forest soil. I’m starting to think this is nutrient lockout? I’m feeding a low dose of nutes(250 ppm every few days) soil could be hot?

Please help identify the cause, interveinal chlorosis since 2 weeks old, no necrosis so far. These two plants are 26 days old. Do they look stunned?
Is this magnesium def since it's going from the bottom? Is it possible the first signs started to show when they were just 2 weeks old? Or is this iron? Or is it smth else? Calmag given two days ago. Pistils show already. I water with ph6.2 but no runoff yet to know the soil ph.
