Maybe, since it was ravaged by mites, and it was in the reveg state, it didn't get to complete the reveg cycle. I know mine that are clones from a plant in the third week of outdoor flowering are similar to yours in shape, and I have some yellowing. My yellowing is the old growth from the regrowth cycle. the regrowth cycle starts out just like a new plant. One leaflet, then the tri-leaflet, 5, 7, 9, etc. (Marijuana Botany, RC Clarke, pp 7 Pre-floral Phyllotaxy) So, some of your yellowing could be from that. The new growth on mine is nice and normal. :twocent:
