450w light. 2000 lol. Gawd, how far can they stretch it. Pretty soon they will be 25,000 watt light (actual 45 watts).
Also advertised as 63.7% efficient while using some of the lower grade budget Cree chips :rofl:. Not even close to 63%!
Dont take my post the wrong way @ad grow I'm not knocking your light anymore than others. I'm sure it's a good light but all inflated numbers like the rest of em do. Not just yours.

As far as your plants go, it looks like you are close to harvest but I cant tell for sure. If you are only a week or two out, I wouldn't sweat it. It would take that long to start seeing it fix itself.
 
In the photo I see a gray tint to the all the leaves. It looks like thousands of tiny dots of gray-yellow color mixed in with pale green.

Turn off the grow lights which seem to be making the whole photo look purple and just use room lighting. Whatever it takes, get rid of the purple lighting and take another photo with white light. I would hazard a guess that the gray color in the leaves will jump out.

My theory is that you are looking at a case of "severe mite infection". There are several ways to check that out.
