Yellowing?

any ideas what this yellowing is from? this partictular plant is just an example . . . it's the lime pheno of chernobyl but it has 3 almost four weeks left of flowering and i am kind of freaked out about the yellowing. i have several strains doing it. it is mostly the inner leaves but i also have several strains NOT dropping leaves.

n defficency?
over watering?
under watering?
to much phos?

my scene is all living organics, teas, and top dresses. i would be willing to use some sort of liquid to correct the issue if i need to.

any feedback is appreciated.

relax its Normal your plant is drawing nitrogen from the leafs to form those fat buds you can give them a light hit of nitrogen 1 time then revert back to your bloom nutes she'll be fine..

The leaves don't always drop, even when their completely dried up and dead, but yeah the yellowing is normal.

do some genetics just not do it? i have a few that arent getting any yellow and the colas on them are thriving and developing weight allready whereas the ones with more yellow dont seem to be packing it on as well.

i allready know my mistake is not mono-cropping my yard lol.
