Yes I do 5m a gal every water and alternate during feeding so when I feed I won’t think she’s telling me she’s in need of some!..

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.

I would focus on trying to get it down a little to The Sweet Spot. The whole plant have Rusty spots or just a couple leafs. Also what kind of pH meter you got?

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?

Now I’m seeing more of this

Do you have a fan blowing on them? Looks like wind damage.

Yes I do I’ll try turn it down and moving it over more of the canopy
