Slow grower. Slightly starting to yellow around the edges of the leaves. I cut nutes a week ago for this one. Gave it a peroxide rinse a couple of days ago. 2 parts water, 1 part hydrogen peroxide. As of today, no additional yellowing and it seems like its not as yellow as it was starting to get but i don't know, it's hard to tell. I'm just gonna keep an eye on it and hope for the best. I added mylar to closet this week. I'm working on a budget so I took a short cut and used emergency blankets. Got a pack of 4 (54"x82") for under 10 bucks, still have a bit left. It's mylar. Easily cleaned, reusable, was easy to put up. Definitely increased the light a bit and gave the space a little more warmth. So far so good.
