I have 3 plants about a week into flowering and I've had this problem most of the time they've been growing. It's mainly one of the plants that has it the worst...the other 2 aren't that bad but still have the same problem.
It's happening on the bottom leaves and working its way up the plants. The bottom-most leaves will get these brown spots with yellow around them and then the leaves will turn brown and dry out and fall off.
The plants are in organic soil and my friend told me that they needed nitrogen so I'm using bat guano for that. It seems like the problem slowed down a bit since I started using bat guano. But it looks like something else is wrong because the browning is still spreading up the plants. Other than bat guano, I use no nutrients. Also, I've just been using tap water. Could it be the water? Would distilled water be optimal?
