The pH is slowly climbing back up into the 6, the fan leaves start getting a bit more greenish, while some of the heavy damaged leaves started to fall off, i assume this is selfpruning of the girls.
@BleuBayouOrganics, Yeah i was thinking it aswel combined with P and Ca, but what is actually happening is that my PH went down in my soil from 6.5 to 5-5.5 somehow. and this blocks Mg Ca and P from being absorbed, Which is the reason of the discolouring. I first thought it was a deficiency aswel, but as it turned out without me noticing, it was because of this that the nutrients are getting blocked from being absorbed, and it seems like there isn't enough in the ground, but i can assure you, there is plenty, a bit too much actually, next run i will start using feeding schedules and go full organic, with the exclusion of pk 13-14 in the last weeks. That way i wont have to bother with PH anymore :)
