So I ran out of my PBP Bloom nutes and grabbed a gallon jug from the store rather than the quart I had last time. On the quart jug it says 2-3-5 but when I looked at the gallon it says just 2.5-2.5. Any reason why these would be different?? Just seemed odd that the same product would have different ratings for different sizes.
My best guess would be that your original nutes are older and possibly they revised their schedule. I doubt that the concentration of the nutes has changed, but just in case you have some light feeders I would probably look into it. Peace
