Not entire convinced that switching your light during flower caused that. I am however convinced that you have a Nitrogen deficiency on your hands. Are you feeding any nitrogen? People say it all the time about cutting out Nitrogen during flower, don’t buy that. Continue Nitrogen all the way through, just not as much during veg. And what type of light did you have before you switched to LED, and how many watts were you running? How high do you have your new LED hanging? And is that 720w from the wall?
First of all i use GHE floratrio. I have been using less and less flora grow in flower as it stopped stretch.
You might have a lockout on your hands. I didn't suspect anything light related because your leaves dont appear to be taco'ing. And I assume that feed schedule was over the course of 5 weeks?
Actually i bought a PH-pen today so i could check it more precise. And as you say, the ph has been a little too high (about 7). So it could possible be the reason for the lockout. So i think i should just ph the next couple of waterings to 6, and ph test the runoff until im happy ?
So you haven’t been ph’ing your feed? That’s problem #1. And you’ve been feeding with every watering? You typically only want to follow that schedule if your using coco. You probably have a significant salt build up. Do you at least water till you have run off?Actually i bought a PH-pen today so i could check it more precise.

And yes. They were feeded everytime in five weeks.
I have only used the fluid with the color chart. But i tested the runoff with ph'd water, and it seemed to be low enough, with a value of 6,6 .
I might think you're right. But can it still possibly be a deficiency, since im using hardwater? But i have ordered some gh calmag now im trying to feed them with
