Not much you can do, this is one of the outcomes when growing autos outdoors....tiny plants flowering.
Next time grow photoperiod fems and in the same amount of time, you can harvest so much more.
If space is an issue, plant the fems late in the season, 4-6 weeks before the summer solstice and the will stay smaller, but out yield any auto on the market when grown outdoors.
Still not to late to put some new seeds in.
When growing autos outdoors, planting about 4 weeks before the summer solstice will give better results, as the days are the longest they will be all year and then they will out perform any auto planted early in the season.
