Plant size?

Normal for me. Keep them growing.

Pretty normal my friend. Like it's been said already, the early weeks are painfully slow (I'm in the same boat right now). They will hit a point where they'll go into hard veg and you'll be looking at a whole new plant everyday. I would take Spin's advice and move to an 18/6, however. If you're comfortable with that. Cheers and good grows this week👍

With 13h of light it's ok , keep in mind that yu'll have a lower yield without the classic 18/6 light schedule , I was growing a lot of autos in 12/12 outdoor and generally they end up around 70cm to 1.40m . It's a bit soon to grow outsoor without a greenhouse if you are in europe

Hey nakre your plant's size looks very typical to me. I wouldn't get too caught up with comparisons though as every plant is different as is every growing environment. Just make sure your plant stays happy and healthy and she will reward you at harvest. Hope this helps and happy growing ✌️👊
