It will be fine. If you had a krausen at some point that means that it's fermenting and that you have live yeast in there. Let them do their job. In my experience with making ciders they never have an extremely crazy fermentation. The thing is that apple juice doesn't exactly have all of the best nutrients for yeasts. That's why apfelwein has those rhino farts. This should be a bit better since it has the PM in it. So just give the yeasts some time to do their job (they are good at what they do until some other factor (typically us) begins to mess with em).
Anyways, RDWHAHB. Don't go jacking around with your stuff. It should be fine. I by default use a blow-off hose on all primary fermentations b/c I just don't want to wake up the next morning with a blown off lid/huge mess, but they're not always necessary. I typically always switch my blow-off hose to an airlock after about 4 days. Most of the time you won't have a need for it at that point.
In summary, if you don't have krausen coming through your airlock, you don't need the blow-off tube. Just leave your cider alone, krausen or no krausen. It should be fine after the suggested amount of time in the fermenter.
Do some "Has my fermentation stopped" searches. Look for some stuff Revvy has said. He's got a lot of info on this forum about this stuff.
