Not sure whats up with my plants :S pics included help

hi
i have a little autoflower grow on at the moment but a few of the plants dont look too healthy was wondering if any of you could shed some light on where i may be going wrong ?? any help appriciated

little dwarf plant bottom leaves are droopy

Bottom leaves are also droopy but feel dry and crispy

Its overwatered bro it looks like its growing in a cake tin with choc cake mix. Stop watering until it perks up and add some perlite next time.

How old is it to be flowering already?

Give it more light and less water would be my guess

This one is starting to flower do you think she looks healthy ??

Wich one is over watered both or just the droopy one as the other one has crispy dry leaves like it has no water

It's about 4 - 5 weeks old and there autoflowers mate
