Shouldn't need to wait although letting them recover a day or two wouldn't hurt either.
You can do either remove a leaf here or there, or all at once and revisit again in a few days.
On larger plants the removal of the top most leaves but not the whole node.
Peel the leaf's finger back exposing a nice spot on the stem to snip. Do this on the highest most leaf(s) protruding from the new growth. You might consider taking the leaf at the next lowest point on the alternate side so 2 leaves. It's all by feel so learn as you go.
I have had success with many plants in a foot². Knowing they will be much much smaller (micro) vs 1 plant in the same space. It can be done but will possibly trade off some yield/uniformity/ease of grow for variety.
