Check your runoff ph and ec to see what's out. Ph a little out can also cause those spots. Adding cal/mg if not needed can also cause other elements to not be available, lockout. High ec also causes lockout and ph out of whack causes lockout. Cheers

Je vois aussi un manque de brassage avec ventilation

Déplace la sur le côté sûrement trop de lumière N'oublie pas de faire chaque jour des rotations

since I guess you are feeding them with same nutrients, I would explain that with a 'position' issue rather than feeding, for example in that particular position she's not getting enough airflow. Have you tried swapping/rotating plants' position regularly?

too much water, bro! let the plants be!

looks like an over water issue, or the roots are bound up, start of root rot... I hate to say it, but I went through a similar spot. I aerated the soil. waited an extra 2 days from regular feeding, and fed with a mix of Golden tree, Piranha Juice, and changed to a foliar spray with the Cal Mag, once that week, and then 7 days later. gave the Piranha Juice a chance to work its magic.

I would say your watering a bit too much maybe, and check your ph levels both in the run off and water. Also if you think your ph is correct, make sure if your using a meter that it’s calibration is correct still. I’ve pulled my hair out before trying to fix problems like this to only find out my ph meter was off creating the entire problem from the start. Bad ph means plants lock out nutrients, as well as over watering will drown them and keep them from needed nutrients.
