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

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
