Flowering stage nut mix??? HELP please..

Hi there well I'm a first time grower(indoor/closet/soil) and I have four amazing plants growing and I'm gonna put them on 12/12 like in a week they are about 23" tall. I was just wondering if its ok to feed it sensi bloom A and B, bud ignitor, big bud, voodoo juice, rhino skin, bud candy and kushie kush in one mix??? to kick start the flowering or is it too much for the first week of flowering??? in veg stage I fed it sensi grow a and b, voodoo juice, rhino skin and super thrive for vitamins and they grew nice. anything would help thank you

Not familiar wiht that particular lineup but I do mix all my additives/ferts etc in the same mix...but if just starting, I would just go in lighter doeses, working your way up in strength on yout brands recommended schedule....

its just a line up im trying to make to see if it works but they seem pretty strong I think because so far i got them up to 600ppm on ferts level and they look fine. I tried using the advanced nutrients calculator but i don't understand it so I'm pretty much learning as I go.
