If the goal this run is to keep them leaves alive as long as possible than I would just add some sidelight. If not enough light is one factor why plants throw off leaves than its easy to eliminate this factor.
I've used 2 EBgen2 5k strips in the party cup comp and have lost not a single leaf in 14 weeks. I've lollipopped her a bit in week 5 and have removed a few of the bigger fan leaves to reduce shaded areas but no more. The brightness level in the bottom area was just 5-8klx depending on the distance(5klx around the stem) and even on the lowest nodes there were small but fully dense nugs and no larf.
I've never tried using sidelights before that comp but I will for sure add some of the LED-tech strips as sidelights(50cm, 10mm wide, 98 LM301b) to both of my areas(veg and bloom). I've found strip housings with clear or diffuse pmma cover pretty cheap(2m a tenner) I can use to avoid contact burnings and make them almost waterproof. I only need a few more of those end caps when I cut each profil in 4pcs á 50cm length.

No, he meant the example I've used againt o show what trees do and why. Indoors we don't mimic autumn and winter, autumn a little but not all of us and cannabis is no tree anyway.
Indoors one of the most important reasons why it happens is not enough light. Add some sidelight and give these lower leaves something to do and the plant will not consider them as useless. I've tested the brightness level around the stem(at soil level) and found ~5-8klx and is was already enough. Only the leaves closer to the sidelights had a lot more light cuz some leaves have touched them but I've rotated the plant every 2 days by 90° to reduce the risk to damage this leaves.
But even the leaves farer away had still enough light to stay green and develope some decent nugs. F...k! I had only half that much trim like usually. That's maybe also strain dependent but I think it has also to do with the sidelights. I need just a few more grows to evaluate it better.
Are you limited to the current lights or is it still possible to add some more sidelights? 2ft EBgen2 strips cost ~7$ and you could drive 5 of them in parallel on an HLG-60 or 80H-20B(~30$). Up to 80w sidelight, dimmable if you want, for ~70 bucks. These strips don't need heat sinks..
