Hi, Would really appreciate some advice on how to stop the cause of these brown spots. Pictures below! I'm on my second growth now, after upgrading the light I'm stunned by the growth of these girls. But yesterday night I noticed brown spots on two fan leaves on my White Widow Automatic, pictured in the closeups. The picture of the full plant is from today. I moved my two plants, the other one is a Royal Jack Automatic btw, to bigger pots 3 days before I noticed the brown spots. Using the soil from same bag as they were previously in, however, this one got about 15% old dry soil from another bag closest to the leca's in the bottom, as I noticed I didn't have enough. I watered it a bit first to rehydrate it. Plant White Widow Automatic Seed 3 weeks old 10 cm (4") tall Soil Ecologic soil for herbal plants, enriched with chicken manure, peat, clay, lime, silicon, iron, magnesium, calcium. Leca in bottom for drainage and oxygen, plus a handful spread into the soil. 10 Liter pots (2.2 gallons) Light 24/7 (Both plants are Autos) 1x Mars-Hydro TS 1000 LED 150W Compares to: HPS/MH/HID:250W 60 cm (24") hanging distance from top of plant. Two white walls, two of natural wood. Ventilation 1x 107 m³/h exhaust fan, grow room is 0.63 m³ 1x Oscilating table fan, at intake, giving the plants a fresh breeze Climate 25-27 °C (77-80 °F) 35-45 RH% (I'm struggling to increase the humidity) Water Tap water, no added nutrients, no flushing, let top 3-4 cm (1-2") of the soil dry before watering I'm planning to improve their environment with a growing tent, for better light reflection and easier climate control. But pretty limited by insane shipping fees to Sweden and a small 61x61 cm (24") closet.
