Potassium Bicarbonate for PM in Late Flower - Safety

[ggrow1]

Good Day All!

I am about 6 weeks into flower in with my outdoor grow. I have used Potassium Bicarbonate to treat PM with great success. I am wondering if it can be used late in flowering without impacting the buds. I've seen some threads on the matter but haven't be able to determine safety late in flower.

Any opinions would be greatly appreciated!

Thanks!!
