Those plants are extremely hungry. That's why they show those multiple-nutrient deficiencies. You need to follow a feeding schedule in future grows that allows for fertilizer up to 2 weeks before harvest, just like Mr. C said. You stopped MUCH too early, but it's too late for this go-round. How long have they been looking like that? I would have been freaking out about 2-3 weeks ago, because that level of deficiency doesn't just manifest over night...
