What's wrong with my plants?

[StuckinTheCloset]

Hey guys im growing hydro and im getting into the end game with my crop. Two or three of my plants are starting to show orange little spots all over certain leaves. A couple other leaves have died off and i think its the same cause. Can anyone help me diagnose the problem? Im keeping the ph steady.

Welcome, @StuckinTheCloset . Good help will be along shortly. My guess is they need cal-mag and/or potassium, but don't listen to the guy who hasn't started growing yet. I'm really just checking to see if I'm learning anything. @Pennywise or one of the more experienced folks will be more help.

Welcome stuckinthecloset, get a magnifying glass of some sort and under the leaves for small dark bugs. It's looking like possible spider mites cause the yellow spotting. Also they look over fed so I would back off the nutrients just a little. Spider mites are a big problem if that's what it is.

Yeah definately too strong nutes mate.
Good shout from pennywise on the bugs there too. Looks like mag def but its in the wrong places so bugs it might be.
Ph Should be 6.2-6.5 can't see the full plant to say for sure but e/c should be somewhere 1.5-2.0 or 700-1000ppm.

Thank you all for your input. I will check for mites and dial back the nutes. My ph is always 6.0 and gets corrected at 6.5 because the air slowly makes it rise

The ph will start to drop once you lower the nutes aswell mate. It will if you lower them enough anyway so just keep an eye out for that.
It's partially root secretions and partially the change in the nute concentration as the plant feeds that causes it.
Once you get the strength dialled in should rise in veg then drop in bloom.
