Since you're in a "hot" soil mix, doubtful the additional nutrients would be necessary, at least till some of the in-soil nutrients are burned-off via time and uptake. I checked, and from the info I've seen, your soil is already buffered. To what ph level...IDK. Do some Google searching for what other users have encountered.
Personally...I use aspirin on my ladies to stress the lady to produce nanners for femming. Not a chance in hell I'd use aspirin in a foliar or feeding solution. Plus, did the poster of that recipe say what Mg tablets to use, or would any size aspirin do...? Since I use the femming with aspirin technique, am curious how close to the stress line that addition will take you.
Doubtful your runoff ph number is even close. I'm unfamiliar with the particular brand of soil you're using, but does it mention lime or oyster shells or anything else that can be considered a buffering agent? (does it say "ph buffered" anywhere on the label?)
Adding lime if you don't know the buffering capacity of the soil is suicide. In other words, if it's already buffered, and you buffer it more, you are jacking the ph too high, and will not be able to rectify the situation. (you can't take it out once it's in)
Old leaves are old news. What does the new growth look like? (pix would help)
Have you got a thread on that aspirin causing a female to reverse and produce pollen to pollinate a clone of itself or other progeny? Aspirin sounds easier than Colloidal Silver.
