@Swoosh, The Gaia Green that i use for my main feeding is recommended to last a month. With Autos running roughly 12 weeks you need to feed from seedling, 4 weeks in typically when she kicks over into flowering, and your last feeding being 8 weeks in. Your last feeding should be 4 weeks out from expected harvest to ensure there are no nutrients remaining in your medium. This will produce a much better product in the end. Photo periods you really need to plan ahead because you still need to follow the same 4 week feeding pattern but she won't flower until the light cycle switches and depending on the strain they flower different lengths. There are also some strains that require more nutrients than others. You really need to watch your leaves and overall plant as she will tell you what she is missing. Keep in mind when you feed dry amendments (organic) it takes time for the plant to show improvement. I've notice for me a week - a week and a half. Hopefully this helps and happy harvest!
