Mixing Nutrients?

During flowering you could be adding 4-5 different nutrients to your plants, so do you mix them in the same bottle?

Say your using Bio-Flores, Bio-Boost, Hygrozyme and weaning off Bio-Vega in the early flowering weeks...
Would you mix all the above into the same ltr of water your about to feed with?
Or do you separate the nutrients into their own bottles & feed each one gradually?

Im thinking you have to mix them together otherwise you'd end up overwatering trying to get all your nutrients in?

Peace

i would add them all if that's what your plants can handle just mix your water with a air stone to keep the water moving so the nutrients don't setel at the bottom of the container
