This is called a budsite, and it means you are in the beginning of the flowering period :) this is where your main cola will grow from during the rest of flowering. It will grow vertically and soon you'll see white hairs sticking out in every direction (above, below, sides). It might be tough on a 12/12 schedule especially since she's an autoflower, so take good care of her! The stretch only happens once so make the most of it.

This looks like damage caused by thrips. Neem oil can be effective against them but the neem oil needs to be sprayed daily on the leaves both on the top and undersides. Be careful when using neem oil as this can cause an unpleasant taste on your buds. You can also try Spinosad products which are organic and non toxic to humans, pets and plants. Make sure to follow the directions on the bottles of either product as this will result in getting rid of those pesky insects. Make sure to treat your soil as well. It also does t hurt to pick up some lady bugs for around $9 they are an effective deterrent for other small soft bodied insects. Hope this helps. Good luck on your grow. Remember the already effected area on the leaves will not get any better at this point. It is best to look at areas that have not been effected yet.
