    hi guys

    bottom feeding these babies in soil every 48 hours using growers ark nutes

    Half way through week 5 so 33 days from the flip

    I’ve taken photos of the worst plant but there’s another one slightly less yellow/discoloured

    any ideas?

    Are certainties always certainly?

    Sorry, I don't know anything about your setup but it looks like you only have about 4 weeks left... What would be your course of action if it's certainly K? ;)

    Maybe just ride out the storm...

    I’m going to add some pk boost if it’s definitely a deficiency
