my plants are in the middle of flowering about 4 weeks in and they stand about 3 feet tall and I'm wondering what ppm their solutions should be at I am running it at about 1250ppm and I don't know if that is safe or if I should drop it by about 150 to 1100ppm or so... what would you guys be running ? oh and nutrients are FloraNova, FloraMicro, Koolbloom, Subculture M. plenty of oxygenation and all 5 gallon reservoirs.
