Welcome ! If you’re already using Cal - Mag I would first start by verifying my pH meter an then get me a runoff and check ph. The rusty spots resemble lack of Cal. or Mag. What was your last ph run off number. ---

Just a few leaves here and there it’s the only plant that has it in the veg room and they all get same amount. My meter is the Vivosun yellow stick cheap one 20$ should I use the solution for now incase the meter is off? ---
