That giant plant is way too big for the pot (soil volume).
Flip to 12/12 when plants are the same height of the pot.
Which is, from the looks of it, right now, today.
It’s a miracle that big one is still alive. 
As above, so below.
Roots need space, you’re growing in soil, not hydro.
Work with nature rather than to attempt to dominate her with synthetic fertilizers (I’m highly skeptical about long term health risks as well, and it is well proven that organic produce contains more minerals and vitamins per weight, plants grown on synthetics simply contain more water and fiber, creating the illusion of larger harvest).
Think like a forest. Feed plants with plants.
Companion crops help keep balance.
And with a stacked pot setup you can then add kitchenscraps, tree leaves, grass clippings, dandelion leaves, nettles, thistle, etc. and keep growing in the same pot for the rest of your life.
It works.
@OniTenshu is also showing how well companion crops work.
