Is the ppm the same as the ph meter? I’m very new with my tower garden and my pea plant is turning yellow
Can you put that in on top of tower garden minerals in water , or do you have to drain everything and start new?
That ppm meter on amazon is $130.00 Not cheap.
Very confusing what you were using and how much. Thanks for trying.
Hi. How often do you add nutrients? I have a tower garden but not sure if I should add more than weekly
What is the website you used to look up the PPMs?
Where do you buy your ph up
