They look fine to me maybe a little under feed. They stop growing about 3-4 weeks from starting 12/12 just give it a little more time.

Depending on how much light leaks youâ??re talking about? What type of light is leaking in? How far is the light source from the cabinet? Those are factors in if you have problems from light leaks or not.

I would guess you would not have any problems at all. There are some that say you will get hermies if any light gets in during the dark cycle but I'm not one of them, and they are wrong 99% of the time anyway.

Worry if it's MH or HPS and just outside the crack and measurable lumens are leaking inside then I would worry. If not relax, do you best to seal the room but don't loose any sleep.
