Can you put nutrient water in self watering bases full time?

Hey all! Working through my second grow and still learning. I have my plants, in week 5 of flowering, on AC Infinity bases. I put RO water with Jack's 321 following Koot's recipe in the bases, ph of 6.3-6.5.

I started getting some signs of nutrient issues in week 4 and I'm trying to rule out possible causes. Am I overfeeding my plants this way or causing nutrient lockout? I've seen other people putting plain water in the bases and top feeding the nutrients, and I've seen some people say they bottom feed their plants but I haven't seen that described in enough detail to know if I'm doing it right. I do water to runoff with plain water + calmag about once a week to try and flush out accumulated salts.

Any advice?
