The symptoms of your plants indicate a potassium or magnesium deficiency as well as a possible pH problem. Check the pH level of the soil and make sure it is in the optimal range (6.2–7.0). If necessary, specifically supplement with potassium or magnesium (CalMag, Bio Grow, or better yet, Fish Mix). These measures should help alleviate the symptoms.

Brown Patches on Older LeavesSlight yellowing and brown mottled patches.
Only on one of the two plants and they’ve been treated and fed exactly the same.
On some older fan leaves, no signs of anything on new growth.
Anything to worry about at this stage? Maybe just a sensitive pheno?
Any advice appreciated.

K deficiency? Or something else?Not sure how to go about this deficiency. PH is solid at 6.5 so it’s not a ph issue. It seemed I had corrected the deficiency when it first appeared a few weeks ago, but now the brown spots seem to be spreading again. I think it might be K but not sure? Any ideas?

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.

I water with 50% distilled and 50% rain OR 50% distilled and 50% tap. I have fed once with Grow Big and it happened right after. Might have rubbed nozzle on the underside of the leaves. I water every 2-3 days and water until drop of runoff appears in tray. How much runoff?
