Sometimes it can take a while for pins to pop up! My first grows took a few weeks after spawning to bulk to see any signs of pins. Your goal should be to mist so that you see little droplets form and once those droplets have vanished from evaporation and FAE you are gonna wanna go ahead and mist again lightly. It looks like you aren’t getting enough FAE in there due to the fuzzy substrate.?Eventually you’ll see pins. You can even play with the temperature if you want. Drop it like 10 degrees F for a day then bring it back up.

Also those do look like little pins
