Since you are entering flowering mode, you MUST fix those light leaks if you haven't already. Otherwise, you'll have all hermaphrodites, or no bud.

What kind of cabinet do you have there? It looks like my C13.

You need to get a blower; preferably 265 CFM rated. Also, see if you can air-cool your lights via the blower.

Also, make sure your water is below your netpots, not touching the netpots.

Good luck!
