should you give big bud to such a small plant? looks like over fert and a pH issue. what ppm are you using?

the issue is getting worse and worse, I've halved all my nutes and cut most nitrogen out. I've got a PPM pen on the way. i forgot to mention she's 5 weeks old

Looks like you've locked out MG with too much N. Maybe even a lil light burn in there too. Hard to imagine light burn with the blurple too though.

my light is 26 inches away from my plants, its a 600W led. temps stay around 19C - 24C, humidity 45 - 55%. have i done the right thing by cutting out a large portion of nitrogen?

Coco is different than soil, let's just get that out now lol. Has it dried out? That's a problem. Knowing ppm and pH are essential too. This is more like hydro than dirt

I haven't let it dry out I water once its a little bit moist (usually after lights off) the problem is i havent been able to check the PPM throughout the weeks, just hoping the PPM pen arrives soon

Most likely just overfed buddy. I would run on half strength nutes until they look better and you get your ppm pen. My initial thought that magnesium is locked out due to overfeeding is probably pretty close. Leave those bad looking leaves on and monitor to see if they get worse as time goes.
