Yellowing leaves near harvest

Hello there just asking when approaching 2 weeks before harvest leaves are turning very yellow this is my first indoor grow so a bit worried.Never had this much yellowing of leaf when growing outdoors sure I know the plant will start to go through its life stage but very concerned this will affect my yield.I will start to flush 10 days out before harvest .Growing in a .5-.5-1.2m grow tent 400watt hps coco -organic soil ph 6.5 feeding 1 a week at 1500ppm using 2 part bloom & grow.Plant about 1 foot from globe a little heat stress but she had a major growth spurt so unavoidable .Strain is white widow.

Yellowing that close to harvest is completely normal, but without pics we can’t tell if theres abnormal yellowing going on. some pics would help, also you should fill out this support ticket just in case so others know whats going on

some yellowing is completely natural as the plant is ending it’s life cycle I will ignore the 6.5 ph that should be 5.8 because correcting that close to harvest may have little to no effect but in future Coco is hydro :wink: and likes hydro ph levels
