So with my exhaust fan turned on to there is too much suction of my tent. I have 2 intake holes, not really trying to buy inline fan. I am thinking about opening the vent on the bottom right or the one on the opposite side. Good idea? Whats the green film called to put over the vent window?

not a big deal imo if the tent sucks in. I have a 6inch blower and only use a 6" passive intake. My tent sucks in a fair bit. If you don't want it to suck in open up those vents.

Thats what I was thinking. I was concerned for 2 reasons, 1. That its not enough air coming in and 2 I didn't wanna take away from grow space

If you don’t have an in-line fan, what’s up with the tubing? That’s why there’s so much suction because it only has that small hole to bring air in. Using the bottom flaps would be a much better option, that’s what I do. Tent still sucks in but not too much. Just be prepared to vacuum the mesh, gets dust build up pretty fast, at least in this dusty city I live in.

They make high cfm kits that will help keep the tent from imploding. You want some negative pressure if you are concerned about odor control. You can also get a variac and slow the exhaust fan down so long as the tent will stay cool enough with the reduced CFM.
