Hey dude - I think u have a combination of things going on here. #1 - if you’re using a nutrient rich (compost mix or other) soil medium then the extra nutes you’ve been adding this early in veg. Are unneeded and yes - likely contributing to a lockout issue. The larger concern however may be the state of the medium itself. Tough to tell by the photos but looks as though that soil is saturated AND compacted. If that’s the case then the lack of oxygen to the root zone and constantly wet conditions will choke out the roots and inhibit growth. Over watering in this type of situation can also manifest and look like any number of deficiencies too. flushing your medium at this point and on this basis might be counterproductive. Think I’d be more inclined to let the pots dry out for a few days - I mean like bone dry. Then start with basic plain watering for now until you see vigorous growth again. Good luck with it my friend👍👊
