So much bullshit so little thread.
I look at the first photo and I see no problem. I look at the second photo and my first reaction is root stress not a lot but a bit of a warning. Look, if you're using Micro Grow Bloom in a 1:1:1 ratio and the ppm is under 500 and your pH is 6 or close, then nothing you see has anything to do with nutrients. Stop focussing on non existent problems and focus on the roots that's where the problem is.
