I don't know where these inaccurate ideas come from, but they still circulate around.
Fertilizer is needed by plants from the day they go in a tank. Plants need food to grow and live, and food = nutrients. In an old established tank a plant may find sufficient but not in a relatively new setup.
I agree with kitten (think it was her) that moving plants from an established tank to a new one can induce shock, due to different water parameters/conditions. I would leave the roots, remove dead leaves to avoid additional water issues, but leave the roots alone and new leaves may well appear.
I would not use CO2, here again without adequate nutrients to balance it will be of no use to the plants. And it means having more intense lighting or again it will not be of value. Read up on this in the series "A Basic Approach to the Natural Planted Aquarium" at the head of the Aquarium Plant section, Part 1 and 2 deal with nutrients, and Part 4 with lighting. I can answer any questions you may have from that.
The CO2 is one reason for the pH lowering. Another is natural biological processes in the tank. And this is likely the problem with the shrimp, they need minerals for their exoskeletons. But please don't mess with pH or hardness at this stage, it will make things worse.
The cloudy water will clear, that is almost certainly the new substrate. Cloudy water is almost never a problem to the fish, so leave them in the tank esp as you say they are looking fine and eating normally. Which only makes me think even more that the cloudiness is due to the substrate. Not a problem.
I recommend Seachem's Flourish Comprehensive Supplement for the Planted Aquarium
as the best complete fertilizer. Used once or twice a week (depends upon how the plants respond), it takes very little. Didn't see the tank size here, but assuming this is either your 10g or 20g, less than half a teaspoon of Flourish is one dose.
