Feeding with self watering planter

I decided to try AC infinity self water and planters. I’m wondering if anyone has experience with feeding through these planters. Do you use nutrients every time you fill the planters or should I alternate between nutrients and water? I’m growing in Fox farm ocean forest soil fabric pots. Any any feedback or suggestion appreciated.

I lightly feed every time I water. However I am use Promix. It has no nutrients to begin with.

I just started adding nutes . I usually stay at half strength.
