Have any of you dealt with the burned pistils from potassium bicarbonate spray? They look pretty sad with all the prematurely brown pistils, but the buds are still swelling up. Hope they turn out OK...
SpicySativa Reviewed by SpicySativa on . Harvest/dry/cure - Battling powdery mildew Hey everyone. I've got some plants that have 2, 3, and 4 weeks left of flowering (Space Queen, Jack the Ripper, then White Widow). I've been battling a very minor case of powdery mildew using a potassium bicarbonate spray (Bi-Carb Old fashioned fungicide). It's been working ok just with a weekly spray (other than the pistil damage). None has showed up on any of the buds or sugar leaves, just a couple shaded fan leaves here and there. I plan to do one last spray of bi-carb a couple days before Rating: 5
