Yellowing Leaves?

[JohnnyRocket]

Hey Everyone, First time grower. I am in week 9 of my hindu kush autoflower. Last night I did my watering with nutrients and bloom like i always do. everything was fine then hour or so later fan leaves were turning yellow. Should i flush for a week or so and cut her down? please help

Ph could be your problem.

Are you following a nutrient manufacturer’s feed schedule?
Because the last week of flower I always expect to see some yellowing in the leaves.

If the plants were mean and green before you watered, I would look to the last thing done.
