ive had good luck with sunshine#4(soilless) so far...it seems pretty solid for the most part, its peat moss & perlite i belive & only has starter nutrients and its buffered with dolimitric lime...so whatever level ph water you put in your soil should be at(as long as you dont need to transplant as ive found out b4,lol)..but if you dont want to deal w/ adding nutrients to your water then the only one i could recommend would be foxfarms oceanic something...people always seem to love that stuff and you cant argue w/ the results.
