Brownish spots on leaves, tried calmag and removed...

Hi @ValleoGrow! There is something wrong with your soil... Do not feed right now, as this would probably lead to more issues. I think you're having a lockout, your rootmass is unable to manage nutrients intakes anymore. In this situation I would flush the medium with tap water buffered at pH 6.2, flush heavily to get rid of old salts/nutrients, and help the medium to dry faster by putting a small fan blowing a continuous breeze on the container's surface. See how this goes after a few days, and go back to nutrients if the new shoots look healthy. I think the problem started with your pH being too high, not acidic enough, so make sure your pH pen is perfectly calibrated and from now on try to stick to the sweetspot for soil, which is ~6.2, anything above or below will slow down the way your rootmass eat nutrients. Hope this will help, keep us updated and happy growing! 👊
