thats funny i use the botanicare problend formula's, no wonder we both get clogged drippers and they are organic nutes, not 100% but very close. i adjust my ph daily, maybe 2wice if i have to. U dont need the full nutes tho. per gal of water i ussually use about 15mL. This stuff is very strong, but i get excellent results and sweet tasting buds without the chem taste. When i top off res. with water i used 5mL gal. i personally love this stuff, very easy to use when u dont over fert. Some one mentioned using the soil problend formual because its got more phosphate. In my opinion its very easy to use, when u see ur plants getting alittle burn back off the nutes and u know where u stand. No need to mesure out 3 different solutions.
