Fastbuds GSC/mills vs plagron

Okay so as good as its going in the tent, the fastbuds gsc are not too happy. they just seem a bit thin in the leaves and branches as far as i like and i dont think its a strain issue. This is all on me so it's all hands on deck trying to get some more potential outta these ladies. They are flowering okay and the plagron one seems to have caught up completely with the mills one. Other than that nothing special. Found a couple spider mites i nuked from orbit with some dr. Zymes, its the only way to be sure.
