Great info thanks. my plants burn at 600PPM's. I started at around 340 then went up50 to 80 PPM each freading.I only feed one time every 7 to 9 days and I water. a hour before lights go off then in the morning when the lights come back on i give them just PH water (abought 8 to 12 oz).I thought it mite help them not get burnt .
wish I could download. your free book but I do not have the room for some crazy reason. Anyway thanks and I look forward to more content ✌
