    I gave up on getting the right mix. Every run I have a deficiency. low, medium, high ppm doesnt matter I consistantly get rust spots on all of my plants. I still get some bud so im just about over it. fuck it I just deal with the rusty ugly looking plants. still seems to smoke ok when its all said and done

    Just to state the obvious here, because no one else has yet. If your feeding your plants and they are getting everything they need n u see early leaf drop and rust spots 9/10 times your over feeding. Your ec is to high. Especially if you see contrasting signs, like clawing and upside down canoes on the top of the plant and rusty falling leaves at the bottom. Nuts are being locked out and the plant just isn't eating well because the salts in the soil are higher than the salts in the root zone, MJ eats when the salts in the soil or water is less than the salts in the roots.
