First time grower here and I’m running into a few problems with my outdoor grow. My plants are currently vegging but they are starting experience some problems. The leaves are showing signs of burning or a deficiency. I think it could be potassium deficiency because the leaves arent that look burnt are mainly starting at the bottom of the plant rather than randomly all over like what I hear happens with burning. I used a small amount of soul po mag today because of its high potassium content. I’m not entirely certain that it’s potassium however and I don’t want to risk making the situation worse by doing anymore. Any suggestions?
