@HerbalEdu, it has already started a little bit with the nutrients Jungle in da Box, I hope that adding CalMag at least matures, it will not be saved. These problems have been bothering me since last year, as can be seen in the growth.
I had the same symptoms with my Tropicana grow i added PK 13/14 and it did help for a bit but then I ended throwing in 80ml of PK in the reservoir a day just to stop the yellowing 😅 and it F##up my EC massively...I have no idea how to stop it either.
