I thought an excess of Ca was causing the deficiency and by adding a huge amount of B I could sap out the Ca. It didn't work. Recovered for awhile but didn't take up enough Ca.
Is orthoboric acid a good boron source?
EDIT: Threw hazard to the wind, dosed with 8ml of 35g of H3BO3 dissolved in 500ml of water to raise my Boron it about .8ppm. Will tell you how things turn out. Might be awhile though, just trimmed the terminal buds on my indicator ludwigia.
I'm curious, how did your experiment come out? I have had the same problems for some time. and looking for the elusive answer?
Is it OK to ad the boric acid in with the micro mix (CSM+B). Is it possible the acid is reacting with something in the CSM over time when stored dry and reducing its effectiveness?
