Well... at least you've got something to harvest ! First grows are a learning experience fosho ! A few issues you have are showing up now and very easy to fix next grow. The previous advice from the WP homies are right on too. If you don't add nutrients during the grow, the water you apply will eventually deplete what nutes you started with. That's what you're seeing now with the yellowing and slowed growth. Your water is super important too, always know what's in it. Not all tap water is bad. I will say, this plant is a great learning tool for growing with out, or very little fertilization. You'll be well ahead of the growin curve on your next grow ! Oh yeah....get rid of the "autos."
