Slight activity after 3.5 weeks

Hi everyone,
Quick specs:
Partial Mash
OG 1.064
S-05 yeast

Ok so I have a primary carboy with a blow off tube. Nothing special its currently around 70 degrees after 3.5 weeks.

I could hear a bubble in the blowoff tube water about once every 3-5 minutes. I went ahead and pitched hops last week hoping that the bubbles would go away.

Well still having a bubble pop from time to time. No krausen or anything on top and everything looks fine. I just wanted to run it by you guys because I worried that the yeast and hop oils are working off each other.

So my question is do you think this will affect my dry hop addiction last week and if so should I pitch some more? I am planning on transferring to the keg in a week but I can wait if needed. My reasoning for kegging next week is to limit the dry hop to two weeks lest I get the dreaded grassy aroma....

Any suggestions?

Thanks!

 

It's just a little C02 coming out of suspension. Keg it when ready.
