I use the entire fox farm line minus flower kiss, bembe, wholly mackerel, and all the dry ferts.
Great success so far but all of fox farms feeding schedules are way to hot even for photos. Depending on the line you may have to half the doses if you're in fox farm soil too.

This is fox farms feed schedule. Its already balanced as far as nutrients interaction is concerned. The only thing is depending on medium and what water you are using it is hot as hell. Peat and full soil mediums definitely need to get cut back by half or more or your ec and ppm will be way out of whack.
In filtered spring water a full dose feed comes out to over 1500ppm. This bit me in the ass with my current run as the build up of nutrient salts was slow and hit me with a magnesium lockout from loading the plant up with way too much nitrogen.
As far as balance like I said if you cut back, cut back equally on everything. For veg i would reccomend half doses in soils on photos and 1/3 doses for autos and during flower keep the half doses for photos and autos.
