sir_isOanswered grow question 4 years ago Well, other than what Roberts suggest, you might have a bit of excess of some things relative to calcium (mag, nitro, and possibly acids), tbh. As those plants look a but "stubby" and crinkly, very dark green, with some spotty discolouration and such too (though not all that much).
So I'd lower some of your current nutrients a bit, and look at potassium and calcium mainly.
