Most of the plants where either directly sown into their pots outdoors i late april or started indoors around the same time and thanks to some decent early flowering genetics they start flowering by early july (highly photosensitive rather than autoflowering) with a few starting as soon as they reached blooming age at aboout 6-8 weeks old (late june). As for blooming ferts i don't give them much extra and just rely on a well balanced soil mix with lots of fossil bone meal added to help those buds plump up.
