Honestly adding or ammending or changing the very nature of a soil ypu have already planted in can be a very tedious task. It id possible but im def not the best for advice in this. As stated the flush helped mine but it was done multiple times to ever get close and i dint have problems til later in the grow.
Do you have any bottled nutes? Access to pro mix or biobizz light or plagron light?
