The two that were fed closer to the correct ammount of nutrients, look TONS better. I fed the rest VERY little. Just another experimental grow. Next grow will have 8 sets of water, using advanced nutrients, because I LOVE how huge the buds got off this bag seed geno. All the tips of the leaves were curling a bit, and getting crusty. Sorry, I should have pre-explained this info. I've been feeding them plain water for the last week. Water Has risen from 8 ppm to about 115 ppm flushing them out.
