m0useanswered grow question 10 months ago Maybe, only one way to find out. should do a test batch and see if anything falls out of solution.
Most hydro nutrients are all made of the same things just in different ratios/concentrations.
The thing that is problematic is the extras they put in to stablelize PH or other none listed additives.
If my knowledge is right you want to mix in silica first and let it rest then add in all the others. Then PH it if needed.
Good Luck!
