Flushing your medium, with plain, PH’d water, is always a good way to reduce the amount of any nutrient in your medium.
With an excess of nitrogen the plant wants to work hard building foliage, and stems, as this is what the plant uses it for. The more nitrogen it has, the more it will try and grow leaves and stems, rather than flowers. Your plant will grow quickly, but it will be weak and spindly.

How to fix a nitrogen excess will depend on the medium you are growing in. It can be as simple as flushing you medium, or, if growing outdoors, you may have to plant crops that will eat a lot of nitrogen. This will help remove some from the soil.
It will be harder to removed any element in soils than it would in hydro or coco, as the drainage isn’t so good and you can risk overwatering your cannabis plants. It is best to do one big flush, to remove as much as possible from the medium. After the flush, let the soil dry out until the pot is light, before watering again.

Nitrogen is an important element of plant growth. Your cannabis plant will take it from the medium, and use to to build stems, branches, and leaves. It is also a major component in photosynthesis. Without it, your plant will no be able to make chlorophyll, which means, it will not eat.
Once you have flushed, or removed your old reservoir, feed your plants again, at lower EC. This will lighten them up, to a healthier shade of green, within a week.
If growing weed outdoors, flushing may be an issue. But you can plant some side crops amongst your cannabis plants. Plant a crop like corn, which is a heavy nitrogen feeder. This will make sure there is less nitrogen in the soil.
