Yep. It's easy to spot- the seedling head just looks all compact and not growing- Sometimes that membrane is too tough for the seed head to open up on it's own- So.. It's usually easy to dislodge. If left on there a couple of days, it can dry and harden- making removal trickier- just take a razor and gently cut slice the membrane off only. Don't damage the seed head or you will kill the pant.
Most of the time you can just push it off with a finger nail. Just don't bust out the razor, unless it's a last resot- it's easy to damage the seed head.
