Clone flowering too soon

I few weeks before I kicked my WW into flowering, I topped her. I took the top 4 inches off and rooted her. She has been rooted for a month now and is almost 6 inches tall in small bubbler bucket under cool florecent lighting. She is very healthy and thriving, however I noticed today when changing her nutes she has a small cluster of about 10-12 hairs in the center. I'm pretty sure she is flowering. There are two other areas further down that are forming a cluster of hairs ( about 4 or 5 hairs) She still is on a 18/6 cycle along with several other clones (which are not doing this) She's too small to be flowering, right? What do I need to do with her now?

Well for sure she should not be actually autoflowering, phew.
But weird, that's unusually heavy preflower development!
You could always switch your veg room over to 24/0 and increase the N to discourage any thoughts of early flowering among your girls.
BTW that plant looks very nice.

So I switch to 24 hours. I don't think I'll mess with her nutes tho. I barely just started her on some a couple of weeks ago, Just a worm casting and kelp tea that was really watered down and her tips fried. My husband freaked out about it. She recovered quite nicely tho except the flowering part.

its preflowers, remember clones are the same age of the mother so it will show hairs sooner than normal
