Lights bleeding from next tent through exhaust

So I have 3 tents next to each other and duct running from one light to the next light to the next being run by a fan in one. Not the ideal setup but it works. This particular grow I am using a new substrate and haven't trained like I normally do so the plants are taller, the lights are higher and more light is bleeding through the ducts to the other tents. So I am wondering, do they make something that I can put at the end of the hood that would cut down on light? I could just through a black t-shirt in there and I am sure it would cut down like 40% but does anybody have any good ideas?

Perfect! Thank you so much. I actually made sleeves that went on the outside out of black cloth and sewed them but that didn't solve the inside. You just saved me tons of stupid ass ideas.

Ducting connecting my 2 tents is about 4 feet
I checked it with a straight tube and sod all light made it through
A curve at one or both ends solves the problem

Are all these tents on different light schedules?

Other than when one is in veg for a few weeks they are all in flower and I used to different schedules because I grew small with more training so there were enough bends it didn't matter, just this one grow I let them go and the bends went away, almost a straight shot through 3 tents. Next time I am keeping them all on the same.
