Troubles. Took about a week to get serious before treating w/potassium additive for the curled leaf. Evo must be more sensitive than other three. After 6 weeks vegetating w/tap of PH8.8 affected all 3 plants. In different ways. Yellow curl leaf supposedly means potassium lack, Evo damage. Got raw potassium to add to watering. Both MDs yellowed mostly with #1, but #2 little yellow but burnt tips. Read nitrogen lack with the bottom leaves yellowing and dying, and yellow keeps creeping upwards. So go also raw nitrogen to treat both plants. AH just looks green without yellow so apparently didn't' suffer as much as other three plants. thin. Will keep treating. Buds are forming for first 3 plants, wk #4 flowering.
