Hey man! Happy growing and good luck with your first. I’m doing the same at the moment.
Your plants look pretty good and healthy. There size seems appropriate for there age. You can see what mine were like at that age in my grow journal.
As for the watering, I’d have to agree. The plants don’t look drowned but the soil definitely looks soaked. Next time you water, stick to the edges of the pot to promote the roots growing outward, and let the soil naturally soak to the centre. Don’t worry about the light cycle. I started at 24, and found I got better growth with an 8 hour sleep cycle when I added it in. It allows the roots and the soils microbial life to balance out.
Keep us posted and good growing
