San fernando Lemon kush,widow , Critical

I am a little worried because I notice that the plants still do not bloom and they have already been more than a week and I measure with the lights at 12-12. I have reduced the dose of many nutrients to be able to use them until the end of the cultivation since this brand is expensive and now I cannot afford to buy more nutrients. -babies: (San Fernando Lemon kush and widow) 64 days The state of the plants are healthy, they are happily growing. i cotinue defolation the plant each three days. i am watering with 750ml (i lost the fight with the springtails) Nutrients: -Excelurator roots 0,2ml -Mammoth 0,16 -advance nutrients sensi bloom a 2ml -advance nutrients sensi bloom b 2ml -advance nutrients tarántula 1ml -advance nutrients voodoo juice 1ml -advance nutrients B52 1ml -advance nutrients bud Candy 1ml -advance nutrients rhino Skin 1ml -advance nutrients sensi cal MAG 2ml FOLIAR -advance nutrients nirvana 1ML -advance nutrients Piranha 1ML -Bud Factor X 1ml Critical(Big momma): 91 days I have been watering 1L.
