I'm not sure if this is nutrient burn or some sort of deficiency. Burnt tips were from possible previous nutrient burn, but now I'm seeing Brown spots and some discoloration. Please check my week to see full details.
I would say maybe a little underfed but always best to diagnose by checking your runoff ph and ec levels to make sure what's going on. This is the only way to see what's happening for sure. Cheers friend
