Why not compost tea for the fungal problems, Elijah? It think it is
touted as being very effective for that. More info at
In biodynamics we use BD501, which is known as Horn Quartz. It is far
from being simply 'silica.' Moreover, it is used as part of a system
and probably would have some downsides if the appropriate groundwork
was not done before it was sprayed. (Can also raise hell with
seedlings, transplants, and cuttings.)
