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.5y ago

What am I looking at?Redish Brown spots, and slight discoloration.
Magnesium deficiency? Calcium? Other?
Gave them a splash of Calmag, but was it even necessary?
OR, should I have just swapped nutes and wait, then correct if not improved? (It was nute day, that's why I ask!)Leaves. Color - Dark-brown

I flushed it because some leaves were showing some Nitrogen Toxicity. Run off was coming at 3000ppm and I fixed it to 1500. Now the older fan leaves are yellowing with some brown spots (check the last picture). It's a deficiency? Should I increase nutes? Thank you very much!Week 8

Brown dark spots on fan leafAny clue what this is? It only appeared on 1 of the plants and only on 1 of the fan leaves. The brown color has kind of a metallic shine to it. My guess is that it’s a Cal. def. I also suspect it might be a Phosphorus def. as the plants turned dark green the last few days.Week 5

Black spots spreading // Need your help!Anyone got a clue what this dark spots could be? It started in a corner of the tent with 1 plant a few weeks ago and now it has spread to another. I suspect pH issues and a nutrient lockout bc of that. Not sure if its the same issue though..Could be an infection as well...Leaves. Color - Dark-brown
