Oh damn! Anymore genius conclusions?

I'm using coco, and feeding according to the head method for coco. I was wondering if I'm getting deficiencies because it's too low light, but idk. Maybe there is a head method that someone figurednout that's good for low light. Like thr 5/10 lucas came up for low light situations.
