Come to my aid

Hey! Plants look pretty healthy, don't see much wrong with them to be honest. No light stress, there aren't any taco leaves (light stressed leaves fold like tacos) Could be nutrient burn like cmstaker01 mentioned, mainly because you can see the tips turning yellow. (main sign of nut burn.) I checked out your nutrient table and it doesn't seem like your giving them too much but still, try and lower the dosage a bit and try it out. They look pretty bushy so I recommend you go ahead and defoliate a little bit, maybe the biggest higher fan leaves. That way light will penetrate to lower growth and bud sites will grow more. Good luck and Happy Growing!😃🌱🌿🌲
