I don’t remember any issues with the b52 I only had it happen in dwc with the advanced nutrients . The flood&drain has treated me right and now so has the dwc proved to be a way to go . My journals with the advanced nutrients are in the completed journals. These two in my signature I used the mc nutrients . Both were the v2.5 nutrients as
@MrSauga can explain. If you go to his journal he just posted the spread sheets on them . My dwc journal is a short one at 15 pages . If you like rosin capsules it’s in there also.
On the build up I would rinse it into another bucket then use the tea mix so it doesn’t have to work as hard . I used a spray bottle with just the ro water rinses the muck right off .
No apologies we are all in this together .
