Growing unknown strain (haze maybe)1000w LED in FFOF and feeding on FF schedule with Big Bloom, Tiger Bloom and Grow Big. Around 600ppm at this point of the Big Bloom and Tiger Bloom. Have a slight burn- looks mostly like N and K. A little burning on the tips and brown spotting around the tips of the fan leaves- dark green with a slight crawl downward on the lower fans. I know I probably have a few weeks left. Just starting to cloud up. At this point do I continue to feed low levels or should I just feed water to leech the soil?
