So I just use a bat guano for the first time. Used less than the suggested amount. Checked ppm on the run off. Over 2000. WTF! My water was only 190. What needs to happen. Do I need to flush the shit out of them?
Run off contains traces of silt, prehistoric salts, and a thousand other ingredients. Don't worry about the PPM of the run off. Stay centered on maintaining PH.
Thanks for the replies. I would have checked earlier but I don't get any notifications that someone has answered. I flushed them all. Figured better safe than sorry. There was a little nute burn on a few. Trimmed some of the big fan leaves to let light at the lower level. Raised the lights about 10 inches. Lowered the fan speed. Seems something is working as the are looking bettter. And a little cal mag as a foliar spray seems to have helped on the spottting. Thanks again.
