. Looks good. Let us know how it turns out. Give her a few days to fill in with green if she doesn't then you know it's a DEF. Nitrogen will start in the lower leaves, they'll gradually get less green until they start to yellow because your plant is sucking the nitrogen out of them for other parts of growth. Magnesium is easy to fix just add a tablespoon of epsom salt to a gallon (or sprinkle like 20 or so granules onto the topsoil and water in. If you don't see any improvements don't jump the gun and give it more, epsom salt is an occasional fixer upper, too much will elevate the sodium levels in your soil and just cause more problems give it 48 hours. The epsom salt will also correct any sulphur def you might encounter. Fish emulsion is fine for plants that old but use it at about a 1/5 strength to start, it says it won't burn but it BURNS even in concentrations as low as 1/4 strength. Good Luck tikitoker 
Thanks man, you have been a huge help in my time of need. I really do appreciate it. And I never would have thought to use paper strips. I always banked on my meters and calibration solutions, who would have known they were off. Gonna go and buy more chem and paper. Im done with the emulsion! Based on the chem test, I have a surplus of N, so I will just "add water" for a while until they start to lighten, then give some N right before flower, that way they have enough going in and for 1/2 way thru. Let them yellow after that for 4-6 weeks and hopefully with cool nights I can bring out some nice colors.lol, smoke another one
