Hi Folks, looking for some experienced advice. Have been growing under 3 CFL lights for a few months now, and my leaves are developing some brown spots. Unsure what i should be doing, or what may be the cause? The seeds were some i found in some bud i purchased from a friend. As i say, 3x CFLs. Also 1x fan for out-take of air, 1 fan for circulation. I water the plants every evening. They are fertilized with a seaweed fertilizer, diluted to about 1/8 strength. this is given to the plants once every 3 days or so. They have been growing for approx 2 1/2 months. Appreciate any advice/feedback etc on the health issues.
