Compose tea how often to feed

New to compose tea just wondering how to feed your plant.
Is it from start to finish? Veg stage thru flower to finish?

you can add compost tea at anytime

I've done it at every watering in my outdoor with great success. Can also do feed-water-feed if you want. If the plants aren't showing signs of deficiency there's no need to feed at every water. Being able to read what the plant wants is a big part of success with growing.

I use compost tea as a flush once a week.

I do EWC tea, and they would love it if I gave it to them every time, but I'm doing it less and less since it's a little extra work to clean the equipment after.
