My okra was really a pain this season. I started with bad seed, not realizing it so I went through several seedings before I gave up and bought seed elsewhere.
Then it grew really slow due to cold weather, but with temps now 95-100F it is really taking off. Problem is it doesn't seem to like it that hot and is aborting new buds, blooms, and young fertilized pods but at least with more energy put into plant growth it will have more sites for buds once it cools down a bit.
Okra definitely builds up momentum. Pretty soon those little leaves will get huge, then the stem they're on will shoot up a couple inches every day. You will have too many plants too close together before long, but in the end it's more about surface area to catch sun than how many plants there are. Unfortunately around here the bugs like to eat okra leaves far more than my peppers, tomatoes, etc., especially leaf hoppers and grasshoppers.
I suspect yours will benefit from water.
