Actually you are only 6 weeks into flower with maybe 3-4 weeks remaining so the leaves should not be turning yellow just yet!
What is your ec/ppm and what are temperatures like?

@HanJ87, Thanks for the clarification mate :)

The yellowing of the leaves is totally normal as harvest gets closer mate :)
This is the plant using up the stores feed in the leaves :)
Perfectly normal at this stage :)
All the best
