If you have used well pre-fertilised soils, then you will easily have been able to go a few weeks without having had to use any liquid fertiliser. Naturally, your pregrowth period should not last too long, otherwise you will have to use growth nutrients. Many growers also continue to give their plants growth nutrients into the first or second week of the blossoming period because this is a sort of transitional period and the plants still have a great thirst for nitrogen and other building blocks for their rapid development. By doing this the plants will also end up somewhat bigger, given that the bloom feed stimulated the plants to switch their attention (and resources) more to bud formation than increasing their size. In this way, you can use your giving of nutrients to play around a bit with the eventual size of the plant. Right now yo have plenty of nutrients, Id possibly flush before switching over to bloom nutes. hope this helps
