They are perfect on track. Week three most people are just starting to notice buds. You got a whole still. You must have patience. I had the same situation on my first grow. Just sit back and watch them grow.
Okay I hope so my first time I'm so paranoid here are more pics the second pic is the other plant that one has big buds compared to the other one but you guys have way more experience so ill wait
Here's a week by week in my current bloom...I think you're fine dude. How much and what types of lights are you using?
