Whats your temps & especially your RH.
The rest of your set-up may help. PH of run-off & how often are you watering & what method etc. a couple more pics, side shot/s of the whole plant may also help, at the moment the leaf damage there remind me of a problem with ph. how have you been adjusting PH?
Did you rinse the plagron soil before use, there may have been something clumped together in there & cause this sort of leaf burn damage,.

Hello, irrigation pH 7 with citric acid,
24/26 temperature, relative humidity 38 65
I did not put anything in the soil

Try taking the PH down to 6.5,. 7 should be OK but is just outside of optimal range for soil which is 6.3 - 6.8. Sometimes a couple of points makes all the difference.
Also. There is an important correlation between tempreture & humidty and if they outside of acceptable tollerance, it can cause damage similar to what you have in one of your pictures, 'VPD-vapour pressure deficit'? damage if im not mistaken. There are set numbers where MJ is comfortable, 'ie- at 75f a comfortable & optimum RH would be around 55%. There are set RH's for set temps, anything way outside of the correct tollerance for MJ will cause damage similar to the large yellow/whitish irregular patches or blotches in one of your first photo's there. This is often mistaken for a defciency. hope this helps!
Peace.......Scroger.
BTW, im not saying it is 100% defo VPD damage but it could be a possibility to consider, i'd look more toward PH of your run off & get that medium down to 6.5 first.

The last time i saw these symptoms, someone had used too much ph down & gave it in a rather neat'ish solution.
