need help 4 flowerin stage

hi everyone well im hopi to get sum help with my dilemma and hope SOMEBODY will reply this time lol. well i saved master kush plants a while ago and theyre now ready for flowering. I have been using BIOBIZZ Bio-Grow 8.0-2.0-6.0 the whole way through, now it does say on the back that its suitable for blooming as well but i have other stuff as well from my pal that he had used from his last grow and its called, FERRO REGIONAL FEED, one is called GROWTH A and the other is GROWTH B and these are specifically for blooming. if i do use the A & B GROWTH feeds but do i mix the 2 together or do i have them diluted in seperate bottles? if i do have to have them in seperate bottles, i think it'd be pretty difficult to make sure that the plants are getting the same of both a & b feeds as i use skooshy bottles. Please, ANY advise would be really great cheers. i have put some piccies on here to let you see the feed im using.

Ferro nutes are good from what i have heard, but all the nutes you have mentioned are for the veg stage, nutes with bloom on the label are what you are looking for as these contain a higher amount of pk than n as opposed to grow nutes where the n is higher than the pk
