Watering strategy for plants in pots to big?

Hey guys, I was just wondering how to water a plant in a pot that is too big for it, as due to a noob mistake I up potted from starter pots (almost solo cup size) to 10L and 12L smart pots (around 3 gallons pots) I started to get a nute deficiency on the right-hand side plants at 1/4 nutrient strength so i upped it to 1/2 which was a little too much as the leaves of the guys in the bigger pots started showing sign's of nitrogen toxicity



I'm running coco 60%/perlite 40% using the H3ad formula for coco feeding daily to 20%-30% runoff (as I'm using tap water)

from what I am seeing the plant that I still have in the little container can handle a lot of nutes but the bigger potted guys seem to get overfeeding symptoms when fed the same strength solution .. is this because the ones in the bigger pots have more to eat from so they kinda snack all day and overfeed themselves? whereas the guy in the smaller pot basically can't overeat due to the fact that he will go through the nutes in his container much faster and have none left to overfeed himself?

should I just water the plants in the bigger pots way less like every second day as compared to every day?

Some advice would be great from the experienced growers here.
