My plants have spots on the leaves. Random leaves are turning yellow. I sprayed the plants with 4 tbs. Dr. Bronners Castille soap in 1 gallon of water four days ago. Five days before that the spots were white and I saw a thrip on a leaf, so I sprinkled DE on the ground around the base of the plants. I cannot see bugs or worms on the plants. Should I spray them with BT as a preventative?
Today I found one rotten bud and removed it. Should the plants be sprayed with potassium bicarbonate? I am such a novice that I need all the help and suggestions I can get.
This was found on a white widow clone in my yard. It is less than 1/8” and barely visible. I only saw it when I saw some buds with small brown areas and cut them off the plant. The plant is in the 4th week of flowering.
Is there something I should do? Can the plant be saved and harvested? Will the plant next to it get the bugs? All advice is greatly appreciated.
