6 week old grow, check out this whats-it on some of the fan leaves - The largest and most mature leaves.

I'm thinking lay off the water until they dry out and water two or three times without nutrients after.

Soil has been testing wet for days so I increase the temperature 2° to 84. Humidity steady at 45.

If your temp is 84 your rh should be 74-78
You're way too dry and plant isn't uptaking nutrients correctly. That's why the soil is still wet.
Fix that first and you will hopefully see the issue resolve.
Those leaves will never recover though.

I'm using 14 drops of hydrochloric acid per gallon Taking it down to what I think is 6.2. It's been 3 years since I calibrated my ph meter, I'll look into it.

Ah ha. I'll fix that temp. It's only a few leaves so far so want to catch it early. Thx.

My meter is reading 9+ in distilled water. Time for a recalibration.
