Thanks for the response. Ive been researching like a madman. My soil is a blend of coast of maine organic and happy frog.Im running the gh flora series with cal mag, rapid start, and armor si. I’m following the “light feed†schedule on the manufacturers feed chart. Im also making sure my ph is between 6.1-6.3 and I've been adjusting my ppm based off of my readings for the age of the plant, right now my inflow ppm is around 600 and runoff ppm is around 650-700. Im watering 2x a week when the soil is dry down to about an inch and pots feel light, im alternating with plain phd water every other feeding. Unfortunately I’m still figuring out the light distance for my leds as Im very new to this.I have 2 sf2000 lights in a 32x32x65 and had them at 18.5 inches which I believe was too close. I noticed some bleaching and the brown spots were from spraying water with the lights on, live and learn. Ive since moved them up to 24â€. I believe the paleness was due to light burn. I bought a cheap lux meter just to get an idea and based on the manufacturers ppfd chart and my meter, it looks like 600-650 ppfd is around 45,000-50,000 lux and thats where I’m at with the lights at 24â€. The back plant looks bad, its an auto that I topped twice because everyone said not to. I just want to see what happens. Thanks again and thanks to nebula haze for publishing all of this great info, I’ve found something In me I didn't know existed
