Can't get a break

[AnonymousGrower2]

I have been giving the calmag. My best guess is potassium deficiency, and it's been getting a bit hot (no control over the building temperature, need to get an AC) so the ones that are deficient have heat stress.
How do I fix this?

..Spiffy, what are the feed dosages, full strength, half--? The pH is important to know, we need to determine if this is a simple lack-of defc., or a pH lockout issue,.. adding more nutes in the latter situation will make matters worse,... How hot? K is involved with temp regulation in leaves,... all these questions I ask are info bits I need to advise, without them, I can't make a solid call,...

So are you saying it's all heat stress? Not potassium..? Totally looks like potassium.

1 Tsp per gallon.. and I think that's too low going by the chart on the bottles. PH is 5.7
Temps got around.. 85? It's back at 75 now. It was just super hot because they kicked on the heaters and I didn't know the valves were still open from last winter. It's been dropping to the 30s outside. So far the "plague" hasn't spread anymore.
