Hi guys ... I'm currently growing candy kush Express from Royal queen seeds ... it says 7 weeks flower time all my other grows have been 8 week plus .. I'm using buddhas trees nutrients but my feed chart is for 8 week .. so would you introduce the pk in the 3rd week of flower as it recommends or would you go in the end of 2nd week of flower as it's a shorter period .. any advice would be good .. thanks guys
