What happened to my monster plant?

Hi everyone,

I’m about to harvest, NL#5 Haze, 11 weeks into flowering, SCRoG setup 400W HPS + 200W LED. Although the yield looks fine, most of the leaves are brown and completely dry. Would that be from overfeeding I know that it’s completely natural for some leaf yellowing towards the end of flowering, but this doesn’t look that healthy to me and I don’t want it happening again. Any ideas?

thanks

Could have been a mix of heat and an imbalance of nutes,looks like a tray under were you feeding to runoff and removing it?

Looks like heat damage to me. Is your extraction fan working properly? Clogged filter maybe?
