Hi all,
I feel like I've been having this problem since I started growing again a couple years ago. My plants will start to prematurely yellow, and develop brown spots. I use Buildasoil 3.0, growing from clones (Free world genetics). These clones were planted on Oct. 29. Straight into the BAS. I watered on top for about 2-3 goes, and then started watering from the reservoir. I saw white roots quickly develop through the watering hole and was confident that the soil was now wicking, doing its thing. Plants are now about 24 inches tall. I use the original size Earthbox, with one layer of paper towels in the bottom to prevent too much from falling thru. At week 4, I top dressed with some build a soil craft blend 3-5-2, mixed with some moist build a soil build a flower top dress, and watered in from the top while the reservoir was dry. This is the first grow that I have been using EM1 mixed into the reservoir, and it shifts 2 gallons of my 'slightly filtered' city water from about 9.0 to 7.0 with only 10-15mL of EM1. I use it every go, but have since started to use fresh water just with PH down thinking that maybe some of the leftover EM1 was building up in the reservoir. I allow a slight dry back period of a few hours in the reservoir per Jeremy at Buildasoil's suggestion. I do not foliar feed or spray my plants with anything. I have 3 lights in my 8x4 grow tent, a 600w Kingbrite (HLG-600H), 240w QB (HLG-240H), & a 300w Mars Hydro (ELGC-300-H-AB). They are set to 75% currently and 20 inches from the canopy. My room is what I consider a semi-sealed setup. I grow in the basement that sits at a cool 65 degrees year round. I filter through one AC infinity fan/carbon filter, and push via another MaxFan w/ 6" duct into the grow space grabbing air from another area in the basement. I open the window everyday to vent some fresh air into the room. Temperature hovers around 73-75 when lights are on, and about 65-66 when the lights are off. I keep a radiator heater going while the lights are off. Humidity is a struggle where I'm at in Colorado so on average about 50% RH right now. I don't have an accurate soil PH meter, but I do use a BlueLab PH pen to PH my water for the reservoir. The cheap PH soil meter I do have is erratic and has shown everything from 4 to 7.5. No insects whatsoever, but I do occasionally fight fungus gnats when the weather is warmer. I've grown about 4 or 5 times like this in earth boxes with the same soil, and clones, and I feel like this happens every time and I feel rushed to flip the lights to 12/12 and get what I can out of them which results in not so good bud. I've been told that BAS 3.0 is a little on the hot side as far as nutrients go, not sure if I should switch to their light version, and top feed, or what. I'm open to suggestions!
