I have been using 50% as a rule of thumb, but that's good info. Keep in mind, this one had about 3 weeks (early) being fed the wrong pH too. There are no signs on the newer fan leaves but I'm watching.
Believe it or not, I do read, listen, etc. I have come up with a new "schedule" I am trying on my younglings. Since pH-ing low ppm water is a pain, I divided up the recommended feeding stuff into the actual NPK nute parts, and the supplements (micro's, microbes, etc.). I'm not planning on dropping the percentage below 50% on the ones that have little to no NPK %
I am going to adjust as needed, probably based on the above, but I am doing the feed, then splitting the supplements into the next two watering's, with the 3rd "feed" just being one of the supplements to give a few ppm to adjust.
The feed-feed-water was based on the gen-hydro feeding schedule recommendation, and after mixing it their ppm per feed was about half what the other three were at the same stage, so I think that was taken into account on their part.
