Too much rain on, want to put bloom on my flowering plants

I have some plants out doors in 25 gallon pots. Gellito, purple kush, white widow. I want to put cool bloom on my plants, but we been getting rain everyday off and on and evening. can I still give them some bloom because the are flowering

Sorry, I’ve been trying to create a post, but I can’t figure out how so I came to the latest post I could find. I’ve seen something about a plus sign, but it’s not on my screen anywhere. How do I post?
