Yellow spots and browning

I have two plants, which were said to be Jack Flash, I purchased them when they were about 3-4 weeks into vegging. I'm not sure of the exact medium, but it's a soil mixture. I've been watering them about every 3 days, and fertilizing with the water every 3rd watering. They've been flowering for just under two weeks. After bringing them to my spot i started noticing yellow spots on the lower leaves. I tried bringing up the magnesium levels, and I made sure i was balancing the PH of the water I'm using, yet it continues to get worse. I included a picture of the leaf i just removed today, it was the worst of the bunch. It doesn't seem to be negatively affecting the plant in any way. Also, am i too late to take clones?

Im not 100% sure on this but from what ive read around the forum i think thats from giving it too much fertilizer. As i said im not 100 % sure tho

might be overfert
for the clones, yes you can but it takes awhile for them to return to normal vegetative growth!!
and risk of hermi

well when its budding its normal to turn yellow because it doesnt have any more N to take in, so it uses the ones in the leafs and its almost ready to chop down, as seedlings and young plants it may be nute burn or the ph in your water is off.

thats not from nute burn/overfert it looks like a deficincy are you giving it cal/mg?

I tried mixing in a bit of milk once when i watered after i first noticed the spots, but it didn't affect it positively or negatively
