hey, this is my first ever grow, using 1 cfl 125w lamp , growing 2 plants , one has brown around few leaves and one in my view is doing very well, tell me what u think as u probably clearly know much more than me, watering every 3 days or when the soil is dry 2 inches down , and another question at the bottom of the pot i see a few single roots coming through the drainage holes, what should i do ?
