Thanks for the advice! I will buy the pH testing drops, plus pH up and down.
I plan to start off with tap city water and let it sit for a day or two. I assume that letting it sit before using it will improve the water for growing plants. At what point in time to I measure the pH and adjust the pH? I'm not sure if there is a optimum time to let the water sit before using it. Would filtered water from my refrigerator or using a filtered water pitcher like Brita or Zero Water be better than using city tap water?
After the pH is tested, adjusted, and re-tested, the hydroponic fertilizer is added. Does the pH need to be measured again, and the pH re-adjusted again? Does adding the fertilizer change the pH. After the
nutrient mix is created, how often does the pH need to be retested and re-adjusted?
Is there a way I can determine when to add more nutrient as the plants consume the
nutrients? I assume there is a way to test for the nutrient concentration.
About how long would the nutrient last before throwing out the mix and starting with a new batch?
