I'm growing 3 vanilla kush. 600 watt HPS cool tube dwc 4 gallon tub pH 5.75 ppm 550-600 4x8x8 agromax tent great ventilation temp72-74day low60-64nights. Nutes were started off low knowing vk can be sensitive. I let them yellow a lil til they needed N then slowly increased .I was slowly increasing nutes .floro-duo a-b two part. Was around 350 ppm then increasing 75-100ppm a day to bring to around 600ppm. Now I have my once healthiest plants leaf margins curling downward. Looking like maybe to much N or low pH. I'm confused. Changed water this morning lowered pH to 5.25-5.5ish ppm in 600's. I'm hoping they straighten out and get healthy any ideas guys.
