What kind of deficiency is this?While lower fan leaves have been yellowing and some of them dying of, the upper fan leaves of the colas with good light exposure show additional dark spots, this developed in only 2 days after watering with plain water (runoff EC 0.53 / 250ppm)
Burnt tips were there before.

More rusty spotsSee this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing.
Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.6y ago

Rusty Leaves3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera.
I also have slight "clawing" on many of the upper leaves.
Mg/Ca lockout because of nitrogen toxicity possible?
Doesn´t seem to be fungi, as there are no spores to rub off.
