Look at the underside of the leaves with a loupe. I think you have bugs, maybe mites. More info about you grow medium, pH, nutes, etc.
 
No no bugs I use super soil and roots organic soil mix but I didn’t have a lot of my super soil left so I mixed my last gro we medium in with what I had left over and new roots organic soil mixed with it the plant was doing wonderful and yesterday night I looked at her and she had rust spots on her lower leaves and 2 nights before I added cal-Meg to her feeding cuz I haven’t added anything but plain water until then so I’m wondering if by me adding the cal-Meg might have done something to her
 
I don’t use any nutrients only what is in my super soil from nature’s super soil compost and mix it in with my roots organic I haven’t had to check my run off my last grow was on point for the most part no deficiency or anything I guess I need to check my run off
 
Yeah sorry typo my phone does it a lot lol but yes that’s what I am about to do as we speak just was seeing if I was doing the right thing by flushing it and just wanted to know what should my run off be when I test my run off with my ppm and ph meter if you don’t mind me asking SoOrbudgal
 
Sorry i don't test never have in my 40+yrs of growing weed outdoors. Don't test my indoor either. Uh Oh guess that means i can't help ya with the ppm an ph meter.
 
If you are using super soil or with any soil you don’t have to check ph as long as you have a well balanced soil. You may need to re amend your soil. Add gypsum and that should take care of that issue if it is a cal mag issue, don’t flush your soil by doing that you are depleting it from nutrients then you will definitely have to top dress. I use malted barley it’s full of enzymes and that help kick start the microbial life in the top 2-3 inches of your soil which should Never dry out.
 
How much molasses do you use and how often? That lowers your pH. I hope you didn't flush yet. Did you look at Weed Pharma's Stonington Blend latest post? It might help you.
