You should never top autoflowers, only deflation. But since they are tiny i would keep all the leafs.
Some other advice, get yourself some new seeds because these plants will produce maybe a few grams at this size.
Next time get yourself some coco soil, autoflower love to have airy soil. Also don't use alot of nutrients since autoflowers don't need that much.
Just keep your medium wet but not to wet so they can grow and flower fast.
Get bigger pots as well and put the seed in the bigger pots. Autoflowers don't like to repot.
