    Haven’t had this deficiency before.

    So I’m having a hard time deciding what this is. I’m torn between potassium def or light burn. Any insight would be greatly appreciated.. they are on day 34 in flo. I’m all organic and I make my soil.

    Not or at least not exclusively light burn. Light burn does not account for the bleaching of the leaves between the vanes. It may be a PH problem locking out your minerals.

      I'm not a soil grower nor organic, but it does appear that your plants either don't have enough K in the mix or it isn't bio-available.

        I agree - This one stumped me recently and cased a lot of stress On Me...O it spreads pretty fast to. increase the K - I resolved my recent issue by adding 1/4 more tsp per u.s gal. I lost track of time line and should of been adding more K.

      PH out of range causes lockouts.

          The artisan spring comes out at 6.3 and I don’t ph because of that. I use recharge. But that’s it. Once a week.
