PPM right around 1050. Plants seem to be handling it nicely, very happy about that. Going to push to 1200 next time, will this be okay with the Hygrozime as well? I vegged this for a bit too long (about 18 inches on average) before forcing them into flower. I have read most of the veritcal growth during flowering is during the first 1/3 of the total flower time. Given that my strain is supposed to flower for 10 weeks, I am approaching the time where they stop growing vertically (hopefully!) I will upload some pictures later, haven't really heard much from the peanut gallery on this thread for a bit, but I will continue to update for those still following! Enjoy!
