Ok...here we go bro. Without even looking at the pics, I can suggest that Alaskan fish ferts by themselves could create some problems. I know for one thing, the goop is 4.5 ph right out of the bottle, they adjust it this way to stop fermentation (bottles exploding on the shelves). I also know that other than macros, it doesn't really add anything but sulphur, are you using tap? So, it sounds like deficiency either way, trace/micros, low ph, or that 5-1-1 is not the greatest veg combo (lacking P & K).
I use fishy ferts on nearly every feeding, BUT I use it in a very different way. By bubbling my mix for 24 - 48 hours and adding microbial innoculants, I get the microbes working on breaking down the insoluables in fish ferts, to an immediately available form for the plant.
Basically, you need a source of P & K in there, to get you closer to 5-5-4 IMO, a kelp or seaweed solution would do this, some earthworm casings and molasses would do the same. Even a very weak bloom solution would get you closer. Then you need to make sure you have your micros covered, calcium, Mg etc.
start with low strenth feeding them with every water give them a rest with just water once a week 2 if watering often.
