So I seen that API pH up down is ok to use with freshwater aquarium and plants. Does anyone have any experience using this product and any effects on plants?
I never used them, but their PH down product uses sulfuric acid…acceptable for cannabis…most fert routines use little of it anyway
The PH up product uses Sodium Carbonate…some say that Potassium Carbonate is better for weed, but I am not an expert. Likely would not hurt in a pinch, but cannabis friendly product like General Hydroponics are readily available everywhere.

They are fine for terrestrial plants.
You can get cheaper items from a supermarket that also work.
Sodium bicarbonate (baking soda) will raise the pH.
White vinegar will drop the pH.
Both of these can be bought from any supermarket for a couple of dollars.
