Guys flowering is in the genetics of each individual plant it has nothing to do with using bloom nutes early.i have used just bloom from start to finish on all my grows and it makes no difference to when your girl will start flowering.i have had some girls start flowering at day 25 and others at day 35-40.
Your girls are looking great izzy bet your glad you stuck with the same feed.i know its hard to break the habit of a lifetime by giving them more and more and more lol
