I have not had a ppm meter for some time and have been feeding based on AN's nute calculator and my plants needs. I just changed my res for week 2 of flowering and 3 days in from that change I am seeing nute burn. So, fine I'll flush and lessen nutes. But, I got a ppm pen today, and my ppm is only 778. I calibrated my meter right before test. So.....WTF....flowering day 19 and 778 ppm is too much feed??? I wish I hadn't even gotten the ppm meter!!! I have diluted res to 550 ppm, pH 5.8, and flushed each plant with Clearex......so we will see if I burn again. Just curious, in all this long windedness, if anyone else has plants this old feeding so lightly.
Thanks!
