Second canopy is a typo my bad
What is the pH and PPM of the soil runoff? What grow light are you using and how far away is it from the top of the plants?
@Mr. Grow It ph of water going in. I need to get something to test ppm with. I just have a aspera ph reader.
@michael.chamberlain4 Ok. The pH going in isn't always the pH in the medium. a runoff measurement will be a bit more accurate.
@Mr. Grow It just ordered one to test ppm. Going to feed today and will test ph of runoff
