Correct. Unnecessary, and can clog the respritory system (the stoma's can clog) Only time I EVER spray, is to correct deficiencies, or kill gnats.
The biggest help you can offer your plants, is to read the ingredients of everything you give your ladies, and get very familiar with those ingredients. How many times are the same components listed as the active ingredients on your assortment of products? Most are likely a sugar beet or cane sugar processed product. (molasses) Some add a little kelp or bat guano or whatever, but the active ingredient in most additives is molasses or urea. Diluted, colored (possibly) and with a hefty sticker price. However they bottle it...it's still designer molasses.
The trick to troubleshooting and correcting isn't in a new product to give the ladies...it's figuring-out which product or combination of products you already use, that is causing the stress. "Advanced" nutrient companies want you to think it's not your fault...but they do have a product to fix that exact problem. (which causes other problems itself)

Keep it simple. All I use is the Fox Farms trio, some Soil Syrup (liquid humic acid) after monthly flushes, and molasses in flower. Oh, and phosphoric acid to adjust my 7.9 wellwater. I still have half a bottle of Sweet, and half a bottle of CalMag Plus I'll never use.

Old leaves are old news. Very doubtful you'll ever be able to restore the original color and vigor to the old leaves. Correct the problems, and wait till new growth comes-in. That will give you an idea whether or not your efforts are paying off.
Your 9 week flowering cycle is out the window. Have you thought of perhaps a re-veg?
