Im not sure what could be the cause of the yellowing, I follow a basic feeding schedule , all my nutrients I use are advanced nutrients; 2ml/L sensizyme & carboload, 2-3ml/L bloom A&B , am I doing something wrong ? I don't like the fact that all the leaves are starting to look like that . Any suggestions would be great. Thanks

I would say overfed rather than deficiency or lockout. They might be under too strong PPFD expressing it like deficiency also. I would dim or raise your light, skip bullshit and go just base nutrients.

Overfed on nitrogen tips only brown, curling back, darker green than should be, lay off nitrogen and bump K up, check ph
