yellow leafs?

The leafs are starting to go yellow at the bottom, anyone help me out please?

Feed it veg nutes.

The only nuetrients i have is biocanna flora and boost

that will be ok as long as the first number is not zero because the first numbers of fertilzer is nitergen which is what your plant needs as long as it is not ready to harvest in the next two weeks because that is natual for the plant to do it at the end of its life cycle do to it has used up all of its nitergen

N-P-K
