Could this be Mg def?

The later in flower a plant is, the bottom leaves start to yellow and fall off because the plant is soaking up all its nutes and energy through unwanted leaves... totally normal. Your plant is focusing on producing buds this late in flower, so all the nutes go to producing buds and not older leaves... 
hope this helps. But it does look like a mg problem... also if the bottom leaves are necrotic like spots on leaves, it could be lack of side lighting...

Yeah I water until there is run off. It usually gets about 1/2 gallon to 3/4 of water each watering. I have been alternating plain water with nutrient water every watering. So it's getting fed maybe once a week. Last time it was watered with plain water. Should I do another cycle of plain water? I checked today and the first single leaf picture in my post that was showing a slight yellow discoloration, has spread throughout the leaf and seems to be almost drying out.

no i wouldnt flush her shes at the stage of life where she eats the most so flushing would be bad. Just water with weaker nute solution next time, like half what you did last time. Test the runoff and if its over 1100-1200 ppm thats your issue. Really i wouldnt worry about it. The plants more worried about buds at this stage then leaves.

I feed every watering, how much nutes i use is based on ppm from previous readings. I keep a running log so i know if theres build up or if there eating right. 250ppm is low but good starting point for you. Id feed alittle higher like 400ppm next time and if your runoff is 1000ppm or lower your plant is eating and the build up is going away.
