Damn locking out..
Any micro feed in the flower nutrients? She has used up all the nitrogen. Cal/ mag needed and showing macro nutrients deficiencies

No sir just added a lite flora bloom to it last watering cause the runoff ppm was 852 was kinda scarred to add much didn't want to burn her up

That run off ppm is not bad, feed her more. And check root zone something is off with ph

Runoff ph is 8.2 but going in is 6.6 I've flushed the hell outta her still coming out the same should I try adding sulfur to the soil?
