No - she's pre-flower but you can certainly introduce your bloom nutes now and start cutting back on the grow nutes. Autoflowers, in my experience, do best if you give the bloom nutes a little early. Also adding a dose of calmag would be good at this stage but only use that once a week...
Good luck...
you can gradually start to change nutrients, in a week that should be a little bud... don't kwow what feeding schedule are you following, but according to that, yep you can prepare to change nutrients this week
Looks like it's in "pre-flower" stage but I'm not an expert. In my limited experience it takes about a week of 12/12 lights before you start to see the flower sites form. I'll defer to the experts on your nutrient question.
