Autoflower?

My plants have been in veg for a very long time. I've just been growing them, I was under the impression they could stay in veg as long as I wanted (I mean mother plants do, right?)

I have noticed all of my plants on 24/0 light cycle are starting to get hairs on them as though they are flowering. This is very strange; I've grown before and have never experienced this.

Any ideas?

it sound like its not flowering yet, this is you plant telling you that it is mature and ready to flower.
is it only the single calxys that have come up so far? if so, it is just telling you its mature. you can flower when your ready.
