Hey guys, I'm a first-time grower and I have a single plant (sprouted from seed). I'm growing in soil in a flower-pot indoors. My lighting is two CFL bulbs, 24-hours, and the plant is doing rather well, except that it developed dark dry spots on the bottom leaves (pictures attached). I've been adding Bio-Grow fertilizer (http://www.amazon.com/Biobizz-Bio-Grow-Liquid-Fertilizer-Listed/dp/B000AXRTEC) every other watering can. A few more things: - The plant isn't touching the lights, I've made sure of that. - The temperature here is comfortable, so there shouldn't be any heat stress - There's a fan that's gently blowing on it, and I turn the plant every once in a while so it blows on a different side. - I'm using tap water to water it. - The top leaves look healthy and green, and I'm still getting good growth (pic attached) Any thoughts on what might be wrong? Thanks in advance!
