Well You can Send Your Well Water To Jacks Or I Believe Theirs A Company In San Diego Called Scientific Research That Will Analyze Your Well Water And Mix Your Nutrients Accordingly.

I Use Jacks Professional At A Rate Of 1/2 Teaspoon Of Each And I Add 2mL Of Extreme Gardening Mag Amp To My R/O Water :weed:
 
Whens The Last Time You Had Your Well Water Analyzed? If Its Been A While It Might Be A Good Idea To Check It Out And Compare It To Your Last Check.
 
First of all, make sure your ph pen is calibrated and accurate.

Cobby, Are you using the well water on other containers/ houseplants without any recent issues? Well/ municipal can fluctuate, but not drastically unless a severe weather event(hurricane/etc).

You said it's just the colder runs that are showing defs, warmer is fine ? , adding more cal/ mag will not solve the issues then.... Raising temps will

Good luck
