Hi mate, yes it's time to introduce the bloom nutes. Keep a little of her veg nutes to transition her over. With the aim of being on full bloom nutes for the feed after this one. At this stage its important to keep an eye on the amount of N she is getting. As they become very sensitive. I dont think you will overdo it at all as she has a nice colour.
Hope this helps and good luck with the rest of your grow 🙂👍
