Limp, droopy girl...any idea?

Hi
I seriously ballsed up this grow at the start, i was gonna start again, 2 of the 3 recovered fairly well but this one has always looked awful. Mephisto super orange haze in DWC under a 200w LED. EC 1.5 ish pH is being monitored ok, i dont think either of these is the problem. Temps 23° RH about 38% i did think mybe thats the problem so i put the humidifier on and that seemed to make it worse. I dunno. The other 2 in the tent are doing ok so i really cant figure it out.
Any ideas chaps?
Thanks

The fan blowing directly on them like that causes increased transpiration coupled with low RH it’s drinking fast. This is causing it to uptake nutrients faster and it doesn’t like the amount of N in the media.

I would raise the fan, up humidity if possible and give it a watering and remove run off. Add no nitrogen if possible for about 3/4 feeds and watch new growth for healthy flat leaves. Then start feeding at a low dose working your way up until she’s happy

GL!
