I’m in canna coco I use H & G PH at 5.8, I started using silica blast and my PH jumps to 6.4, should I bring PH down or leave it at 6.4? It was a freebie so not using it, no problem, your input is appreciated.
I actually use silica blast as a ph up. I will use silica blast as an up as long as I do not go over their recommended dosage. I will usually switch to ph up when I get to half the silica blasts dosage (about 1/2 tsp per gal). I believe silica blast works. My plants seem to be stronger/harder with the silica. Plus It cut my ph up us age in half!
