wHat nutes to give at the start of flower?

Hi everyone i got a few plants ready to go into flower i have ph perfect sensi grow and ph perfect connissuer i was just wondering if i should give the plants grow or bloom nutes during stretch or a mix of both i also have bud blood to start. i am also growing in coco if that makes any difference.Any help would be awesome

The first few weeks of flower I give even amounts of veg and bloom nutes. Backing off on the veg as time goes on. If I start to see lack of N I feed it to them usually a quarter tsp per gallon to help keep them green until week 6. Hope this helps.

I continue fertilizing with veg ferts the 1st 2 weeks. Then I switch to a 50/50 veg/bloom mix the next 2-3 weeks. Then full bloom until 10 days before plain water. I've found this helps keep them greener (and healthier) longer in flowering. But let your plants tell tell you by watching the leaves and coloring. If they are too deep green after a couple of weeks, cut back the veg ferts. If they lighten up to soon, increase the veg ferts. Also, much of this is strain dependent. Every strain likes it a bit different.......
