Greetings,
New to cannabis cultivation in 2020. Still traversing this mountainous learning curve by making mistakes (doh!) and seeking help. I'm growing with the apotforpot kits, both 2 and 5 gallon sizes.
I purchased the cheapest pH pen I could find (mistake, I believe), a Vivosun pH meter & TDS meter for $19.99. The TDS meter seems ok, but the pH meter requires frequent calibration (every 10 days as recommended by Vivosun) and persistently drifts when attempting to take a reading. The instructions say nothing about storing the electrode in a solution, and in fact says to dry before storage. At the same time, it warns to not allow the electrode to dry out.

- Anyone else have similar experiences with this meter, and perhaps determine a better way to utilize this meter?
- Recommendations for alternative pH meters?
- If I'm starting with bottled water with 0 PPM, how can I get around the lack of buffering issue when trying to adjust the pH for my "no nutrient" waterings? One drop of pH Up sends me to alkaline city, and a drop of pH down to correct that causes the pH to plummet.Similarly, when trying to adjust a low dose (2 ml/gallon) Cal-Mag solution or low dose nutrient solution, I have the same experience.
- Are these pH adjustment problems stemming more from the pH meter or my pH adjustment procedure?
