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...

Rusty Leaves
3 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.
