What's that strain you're growing?
They're not quite ready for the chop just yet mate, the buds are still a little white looking. It doesn't really matter about the hairs, when the bud starts forming a lot of the hairs will turn orange anyway you need to wait for em to fill out a bit more. It takes time for the plant to recover, you've only flushed last week and it needs time to repair itself. Also, if it's towards the end of its life it'll start yellowing and eating itself anyway to suck in all the nutrients so the buds get their last swell.
How old are the plants?
EDIT:
Also, because they got nute lock out they're not going to grow. That will also add a couple of weeks onto your flowering time, even with auto flowers. It'll probably need to recover, start flowering again then it'll finish in how ever many days you're supposed to have left.
