Sulfur Smell in my DFH 60

I just transfered my first attempt at DFH 60 to secondary today. Got a slight sulfur smell. The last time I smelled this was during day 3 thru 10 of my Apfelwein.

Is this OK?? This is the first time I have smelled this (other than Apfelwein).

I followed the HBT recipe exactly. I got low efficiency due to the crush - pretty certain. OG was 1.060. I used WLP001 with a starter. After 8 days, I'm down to 1.011. I transferred to secondary and am now dryhopping.

Should I be concerned?

No, it is unusual to get sulfur from WLP001, but not unheard of.
