Yellowing advice!

[dracodragons]

very difficult one here as I think adding more food will cause problems…your tips are burnt to a crisp which denotes soil toxicity…pH is a little too acidic also…personally you should be aiming for 6.7/6.8…if I was in this position I would flush plain pH adj water through everything and leave 3 days to try to remove toxic buildup of nutes and molasses…add some nitrogen to your first feed once dry and assess what the plant needs visually from there…you can’t make a diagnosis fully online…personal enviroments and growstyles are all different…
