Bhizzle28x,
I see what you are talking about regarding the ends of the leaves.
There is some common documentation out there that suggest nitrogen excess. You plants are very green but may not be overly green.
What is your cultivar?
I'd like to read more about others' experiences & knowledge about the praying leaves trait being reserved for genetics with sativa lineage. Is that common knowledge? I would suspect this is not a Indica/Sativa thing but I don't have direct experience. My chemdog prays like a pastor when the pH is right. It's easier to get right in soil than it is in coco. I have never mixed coco and soil before.
When I want to know the pH of a medium in a container, I create a very specific mix such as 150 PPM and the exact pH that you expect the medium to be. Then, evenly and slowly pour enough of this on the medium to produce a large volume of runoff. The amount of runoff should be a marginal percentage of your container size but not so (too) much that would dilute the runoff sample that you will be measuring. Measure the pH of the runoff. Maybe the pH of the runoff is not what you expected.
