Purple Haze #1

I forgot to take more pictures this week, but the fungus gnats are finally gone. Now I have a new issue, though—I think I may have overwatered a bit, but I'm not completely sure. I repotted into 9-liter pots and set the exhaust fan to 40%. Initially, I thought it might be a nitrogen deficiency, but that surprised me because the organic soil from Sonnenerde should provide enough nutrients for the entire grow.
