Hey there i thought it looked like mold at 1st too. A good trick to properly identify the bugs is using a little thing called a bang board, basically a small white board and go check various parts of the plant. Take a bud and either tap it with hand over the board or bang the bud onto the white board, any bugs there are will typically fall off and you can identify the pest with some magnifying product.
If mealy bugs you can get them with rubbing alcohol, ladybugs, and some insecticidal soap. Happy hunting.✌️
