i have started to put schults cactus plus 2-7-7 in it and by the next day some yellowing started to occur now 3 days before the nutes i found a lot of little leaves from the side branches yellowing and some of the big fan leaves brown spotted
i dont know if its too much nutes or it is a N deficiency because of the npk formula of the fert
plz some advice i am worried
thanks
