well, I think my problem with the high PPM's is that I was just going by the bottles and not aiming for a certain ppm. During veg, in a 10 gal res, I had like 700ppm. But I'm still using the same ml per gal so I dont know why it turned out so high... I did delute the 1700 though, I managed to not be careless enough to just plop em back down in that radio active shit.
