Did you give the Fish Shit to any other plants? If you had a reaction in a jugs using that stuff, my guess is that it is to blame. If you have a foul smelling Rez, then your Roots could have root rot and sitting in the Rez is making it worse. Lack of oxygen will make root rot get worse quikly. I personally would throw the plant out. I would dump the soil out and then look at the roots. Also, less is more. It seems like you are doing a lot to your plants before they are even that large. Sometimes adding too many things too quikly is a bad thing. I try to add things 1 at a time and make Changes 1 item at a time. If you add 3 new things all at once, how can we know what is working optimally? Please dont take this the wrong way, but you are running too many ecperiments...without a baseline. You need a baseline grow or 2. Then you have an accurate idea of what your plants should do. Making tons of changes is hard to do and then diagnose problems ate harder. Dont use "free shit" just because it is free. Do a few Earthbox grows without much added. Test new products on only 1 or 2 plants. If something goes wrong, only thosr plants are effcted. Good luck, slow
