Is this fermenting?

Is this fermenting? Or am I still at a lag stage?
On day 3 it looks like I have a healthy krausen, but no airlock activity. Doesn't look particularly turbid in there but I can see some bubbles rising through the FV.
Using WHC Labs LAX yeast at about 17°C.

Yes it is IMO and quite healthily.
Your airlock is not always a indication of fermentation, you could take the airlock of and re-insert it will be a poor connection

Yep it is. I hate those airlocks. I use the s shaped ones exclusively.

Yep. That's it . I swapped it out. I'm surprised, it looked snug. Got some activity now!
