usually using Earth Juice and General Hydroponic nutes, I'm currently using the full line of Fox Farms nutes, including the Open Sesame (5-45-19) ,,, despite the alarmingly high numbers, I have experienced no burning (I'm following the Fox Farm schedule-recommendations of 1 teaspoon Tiger Bloom + 1/4 teaspoon Open Sesame + 1 tablespoon Big Bloom, per one gallon) ... NO problems whatsoever, this is the healthiest, BEST-looking foliage I have ever grown in my life ... my ppm ranges 1100-1200 ... pH is running low right now, but plants are still loving it ... maybe everything will turn to shit at any moment, but she gets chopped down in 2-3 weeks, and so far, it's FOX FARM for me ! :thumbsup:
