@sandune definitely ignore anything I said about boosting N. You’re on the path, just a light thing. For what it’s worth you won’t see this bleaching improve. You’ll just see it stop worsening. Once your plant is bleached that growth is gonna stay that way. New growth will look proper tho.
If you wanna see a bleached out plant that still yielded just fine and great quality check out my indoor grow journal from this past spring.
