Small flowering in winter, outdoor

Is there any possible way to make the buds bigger and the plant bigger for the buds? I am currently 1 month and 2 weeks into flowering. The plant looks beautiful but small. I'm looking into make my yield bigger and theres no info on a outdoor winter plant. I know that the sun hours are cut. Is there any tips that anyone could help me out with? Thanks

at 45 days in flower outdoors I'm in the thought that there is not much that can be done, pretty late at this stage to make any drastic changes. make sure it gets all the sun possible.

Yea all you can do is pray bro. Maybe look up some weight building nutes!but for the most part it is what it is most winter bud is fluffy!
