Hermie or something else?

Hey guys, I could really use your help on this; it's my first grow and I dunno if I'm freaking out for no reason or not.

set up:
1x no-name bag seed
2x Jock Horror (Jack Herer? Is there any difference in the strains, or is the only difference what the seed banks name them?)
3x Northern Lights
3 weeks into flowering
600 watt HPS
DWC hydro set up

If you look at the last pic I uploaded, what the hell are the bulbous things? I already had one mid go hermie, did this girl do it too? :/ I'm not sure though cause it looks different; did it maybe get pollinated by the other herm? Or is it something stupid that I shouldn't be freaking out about?

also: can I harvest in batches? These girls are starting to get outrageously tall and the main colas on the NL are ready for harvest, but the lower branches aren't. Can I chop off the tops to expose the bottom branches?

(All the pics are of the same girl, my tallest JH.)

thanks guys!

WELCOME herasi, to me they look like seed pods, if so you may want to get rid of or could chance pollinating females,
others will most likely give there thoughts also, so wait for replies if unsure

I agree those look like seeds but the other buds look good
you might have male parts in there somewhere if you have pollination

seed pods wont pollinate..
pollin sacks pollinate.
they do look like seeds though
others with more experience will tell you what to do
lookin good tho!!!
