Strain is moonshine's ghost train haze week 6 of veg. Doing dwc in 16 gal tote. PH is 5.9. Raises .1 per day. Res change once a week. Ppm was set at 561 with a TDs 3. Dropped to 500 in a day which tells me to add more however looks like I have nute burn and nitrogen toxicity. Light is 600 watt dimmable mh/hps. Aircooled with 435cfm fan. Temp for today was hi-75, low-65. Rh hi-61, low-39. Using GH flora trio except I'm only using micro and bloom because I'm trying to cut back on nitrogen. Any thoughts?
