I agree with a tad too much nitrogen. Worm castings are pretty hot, as is guano and manure. The plant looks pretty good but I would cut back on the fertilizers. Many of these nutes and stuff are designed for large commercial grows that have large plants with tons of leaves. If you have a smaller plant, you don't always need a ton of fertilizer to keep it happy. Too much nitrogen also promotes more chlorophyll, which is a large part of the harsh homegrown taste that I remember from younger days. A slow dry and cure should remove most of the chlorophyll, but the less you start with, the less you have to worry about during dry and cure operations.
On a side note, I see the silver flex vent pipe near the depressed leaf. If the leaf is getting a stronger light source from the reflection than it is from the light (because of shadows, etc), then the leaf could turn towards the stronger light. I ran into this problem when my plants grew taller than the level of my light, and all of the leaves above the light were clawed downward, maximizing their light exposure. I doubt that is the issue, but they can grow funny trying to get the brightest light exposure.
