Plants turning yellow day 31 flower

[Ravenous]

Hey

so curious as to what is wrong with my plants

I am on day 31 since i flipped to flower
Using advanced nutrients organic line (bloom juice ,bud candy, big bud)
i did switch to flower nutes too early as i learned i didnt wait the 1-2 weeks after light change
ph 6.5 ish when feeding have not checked run off yet i am watering tomorrow
seems like the whole plant is starting to yellow bottom up
lower leaves turning yellow and limp then brown and curling
i do have the smallest amount of burnt tips cant see it in the picture its rlly not bad at all
not sure if i need calmag or more nitrogen or i leave it alone i dont wanna mess it up

i know it does not look that bad but i can see a noticeable change in the leaves colors from bottom up and it seems to be getting worse all 3 of my plants are the same way
not sure if i am nitrogen deficient because advanced nutrients bloom has nitrogen and i do have tip burn

Can happen from potassium or nitrogen, but likely nitrogen if you swapped to bloom nutes right at flip. While bloom nutes have N, it's at a way lower percentage than veg base.

Your plants will continue to yellow so don't freak yourself out too much, if the buds look good... all is good.
