This is the most recent leaf. At first it looked healthy, but it seems like it grows yellow at the edges and has a slight white colour to the very edge of the leaf. I don't really have a lot of experience with growing plants so quickly, especially in a system such as this. I hope someone can help me fix the problems with my plant

I'm sorry, I know nothing about your question, but there are forums here for hydroponics and one for bananas, I believe. If you click on the Forums link on the menu bar you should find a comprehensive list.

Those brown spots are normal on the banana plant especially on the Cavendish variety. . It will lose them when it becomes mature. Now the silver strips, I haven't seen those.

Yeah, I wasn't too sure where to put this question.
And thank you, I was slightly worried as they are all over my newer leaves but as long as they aren't a sign of impending doom for my plant it's fine. Is the yellow edges of leaves signs of some sort of general deficiency- like a calcium deficiency? Since it is in a tent, maybe it has used up all of the carbon in the air and that's why it is turning yellow?

No way to use up all the carbon in the air.

You need to go to the Hydroponics Forum because those folks are familiar with the growing system you're using.
