Outdoor Plant Yellowing, mostly contained too the bottom third of plant.

I used the Fish emulsion and it seemed to work well. Here are some new pics. There is some occassional brown spots on some of the leaves, even up top. I'm wondering what that is. It could be the plant cycling out the empsom salt mixture I gave it, I fear it might have been too much. But that was over a month ago. Generally it looks better.

with the fish emultion you dont raise the mix. stay at 1/4 mix and instead of increasing the mix just feed it more often instead.
look for some blood meal and bone meal if you want some good food for them, worm casting and you have a pretty much complete diet
