chasv77answered grow question 6y ago IMO, you are seeing those leaves being denied nourishment for the good of the plant. Assuming nothing external causing this.
You could clip those leaves, but they will eventually shrivel and die, anyway.
All depends if you like things neat and tidy looking.
Some plants do this, as mine is right now. Keep on truckin, as the new growth tells you how the plant is doing, at this age.
