Which grow is this? Which diary? You can ask questions on your diary page (down at the bottom) and by doing so link the diary to your question so we don't have problems identifying the correct one! NEXT time!!!
My concern here is that you're saying you transplanted this little one... Transplanting requires time for the plant to readjust... sometimes, if your timing is perfect, autoflowers just carry on.... other times, if it's done at the wrong time, their cycle has been disrupted to the point where they may not be able to recover. The only thing that is going to answer this question is time itself. Because you don't know for certain what kind of veg time she requires. I wouldn't stress about it - what's done is done and you can't "fix" anything so just be patient and wait her out... she may go into flower next week or she may go into flower in 3 or 4 weeks... Meanwhile, just keep giving her the veg nutes (you might add 1/2 a dose of bloom nutes to nudge her along although I don't actually think that would do anything - but it won't hurt her).
Patience is the key... Good luck!
