Citric Acid?

Can you use it on buds late in flower?

I'd hesitate to use anything late in flower but it's a much better alternative than any oil based product or some of the products that say safe until day of harvest. Regardless of what is used if you have a bad bug infestation that requires spraying anything on your plants late in flower it's a good idea to wash your buds in plain water after harvesting to remove as much residuals as possible.

3 tsp may be too much so start with 2 if you use it.
