Potassium def

Looking at the def guide I am leaning towards a potassium def so I need a good potassium based nute any ideas, please.

I have hammerhead pk4/8 ???

pics....................

What u think???/

Anybody???

Looking over watered what size pot are you using?

What nutes are you using??

It's on nft table in 3 inch rock wool using ecolizer nutes I'm flushing with just pk 4/8 right now

I really notice the color of that plants stem and branches. Purple/gray? Not a color I recognize as healthy. Lacking experience growing, can't hazard a guess. Hope you get it turned around.

I've been growing roughly 2 years so yeh quite new to it all really but all the advice is slowly building my knowledge

My first grow, one plant. It's doing pretty well but has issues. Not life threatening ones but issues I'd like to know so I don't repeat them or make them worse. After reading lots and having a pretty experienced grower friend check I "think" I know. My learning curve is still way steep right now. Before I began I started reading and damn near every search I ended up on riu. So I joined after having lots of help reading others experiences. I hope you get some helpful info.

Pics what s wrong , temps,rh, lighs

Temps are generally 25c unless it's red hot here rh around 40% lights on 60% lights off lamps are 400 superveg to be honest I dont think it's conditions but hey I'm asking for advice

well it shouldn't be a nute imbalance unless your ph is off

look over-watered to death
