I just tried out FF Grow Big at 1/4 strength (1/4 tsp per gal) on one of my plants and it lowered the pH of the runoff water to 5. The original runoff was near 7 and the pH of the nute/water mix before I poured it on the soil (FF Happy Frog) was a little under 7...
I even tried pouring the same 1/4 strength nutes on brand new soil that I bought today and the runoff was still around 5.
I don't understand why this is happening... From what i've read so far on growing it seems that most people just adjust their water/nute mix to what pH they want and then just pour it in. Is there some sort of chemical reaction taking place between the FF Grow Big and the FF Happy Frog or is this just normal for most nutes and soil? If it's not normal then what am I doing wrong and how can I fix it?
