That's what I thoughtLooks like nitrogen tox.
They look healthy otherwise, they're growing. I just gave em a watering with mild pk boost, big bud, 300 ppm total mix until runoff.We need pics without funky colored lights. Not yellow. Nor blue. Or even blurple. But, white.
It's so much easier to tell if there's other issues when they're viewed in a more natural light.
Well that's a standard shop light, that's the clearest it gets for these, there's no natural light in their life.I only say natural light in case there's another issue. It's hard to diagnose discoloration under lights that are yellow and stuff.
Ok, so was that 2nd picture good enough for you to assessI'm just saying it's one of the first things I learnt here. No one can diagnose your plants properly. Unless we can see them in a more natural light.
Right, it's my signature creation, tell em to hold out their taco in the downward position, free as a leaf in the breeze, and hold it there...Thread title had my hopes up for a new yoga position with pics ......I was totally off
Especially on the taco part
