hey guys please help

hey i have bubba kush growing outdoors and they barley started to bud,,,, i noticed that they heve lots of leaves turning yellow,,,, every day im plucking off at least 10 yellow leaves i have 6 plants,,,,,,,

Probably low night time temps.

My opinion; You're just gonna have to give them more time for the buds to fill out. And hope any hard frost stays away that could burn them up until they're ready. If they had a full growing season I'd stay away from that strain next year. The location is either too shady or the strain needs a longer growing period. good luck.
