good evening rollers,

I'm having an issue the I need some advice about. For about 4 days now, small brown spots have been developing on my Lemon OG lady's canopy fan leaves, only the very top leaves at the moment. Also older fan leaves toward the bottom have been yellowing very quickly, browning on the edges then falling off. I figured the yellowing was due to fact that I am entering week 6 but I think I may have a bigger problem. Right now I feed on Saturday and water on Tuesday/Wednesday depending on the pot weight. Dyna Grow bloom nutes at 1/2 strength mixed in rainwater/distilled water. My guess would be cal/mag deficiency but I'm a rookie so I'm seeking assistance.
