Brown spots on the leafs [RESOLVED]

Ive been saying all of this from the start! If I could have done it differently! I would have! I would’ve bought a bigger hydroponics system and buy a tent and just do all the work I’m doing now! But have more and get more rather than just one plant. I’ve spent over $500 to get my plant just right now in this expensive box! Trust I got the window one :unamused:
