Good luck to you, but i can only really say that this makes me smile. You're wondering whether the added nutes in the soil will harm your plants (without yet knowing) so to counter what you don't yet know you're going to dse them with something you are equally unaware of the results of.
Here's a wacky notion. Leave your plants as they are, then you will technically have one variable to be working with. If you don't know if the soil will burn your plants, and you don't know what B1 will do, what conclusion do you possibly hope to draw. You will be left without knowing if it was one or the other, you damaged your plant and learnt nothing. Until you know exactly what is going on, it makes no sense to add alternative conclusions to a plant problem.
