The plants are stressed AF and after more research from being here I'm seeing the problems. I got another fan and put it on the intake duct so that air was being actively pushed in rather than passively from the other fan which only takes air out. And then I got a photometer app called photone. So I fixed it until it read 100 on the PAR meter which the guys at the grow place told me was good. Now with this hygrometer I can pay attention to this and maybe set up alerts for when the VPD exceeds a certain range.
