waaaaaaaaaaaaay too much fertilizer. You see how the tips of your leafs point downwards? Also the leaves look super dark green which also indicates nutrient toxicity. I only Measure E.C. so i don't know how much that is, but it's obsl too much. Lower the nutrients, maybe try 1/2 strength and look how it develops Good luck on that!

My tap water is about 400ppm(yeah it's pretty hard lol). You have other issues going on. I suspect your pH has been running way outta range for awhile.
