GMSgrowsanswered grow question 4 years ago No diary. If you add cal/mg already and you see this problem still then you could have some lockout starting. If you arent using cal/mg then you need to add a little once a week or 2. Lower your other nutes to maintain the proper ec level so as not to overfeed. Check your runoff ph and ec levels and make sure it's not something else going on. Cheers
