Random Yellow Spotted Leaves
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.
Thanks in advance for your help and advice!

What is the PH of what you feed it? Is that an Outdoor grow in soil? Those buds in the picture dont look big enough for bud rot, where the ones you found about the same size or much larger?

Looks like septoria leaf spot . Not much you can do in flower, but remove the infected leaves. This is a BIG problem OD !

i dont know how you outdoor guys do it!!
for sure, like the guys have said, check your pH (start with the basics)
doesnt really look like a bug infestation but if you saw insects, i would personally go out at sunset and put about 100 ladybugs on the plant. if there is food (thrips,mites,aphids) they wont go anywhere til the food source is gone

also 4 tablespoons of insecticidal soap is WAY too much. soap kiils an insect is the same way it kills plants. suffocation
