Runner bean plant not getting any taller?

Hello. Newbie grower and member of the site here. So I'm noticing that my month old scarlet emperor plant hasn't been getting any taller for at least the last week, or if it has the height growth has been negligible. It IS growing lots of nice green leaves, but shouldn't it also be getting taller? Is this a normal phase of its growth cycle or is it lacking in something?

To give some history on the plant in case it's of importance, it was one of four seedlings. They all showed signs of chlorosis at about 1 week old so as instructed by someone I applied iron chelate and fertiliser (diluted by half). I think I did wrong by sprinkling the fertiliser on the leaves as well as the soil as three of the plants' leaves suddenly went bad after that (chemical burn/leaf scorch?) and eventually died. This one plant survived though by growing new leaves. But I'm starting to wonder why it's not getting taller even though it otherwise looks very healthy?

Thanks for any advice.

Just guessing here:  I wonder if it's using its available energy to repair or replace its leaves.  If so, vertical growing could start soon, since it seems to be doing well with the leaves.

I'm not actually familiar with this problem, but it seemed to make sense.

it looks like it's getting its vine-act together and is about to push.

It might be putting a lot of energy into root development, too, especially if it suffered some damage. I wouldn’t worry.

You guys seem to be right. It seems to be growing upwards now, yay. Never thought it could just be recovering itself so I learned something here too. Thanks!

I also think it's just getting started, I know when I planted mine this winter they took a good long while to get going (longer than I would expect pole or bush beans to take).

At least the traditional scarlet runners I raise (can’t comment on others) make a nearly tuberous root to the point you can dig and replant them. They can get a little swallowed in some settings because they have some delay compared to standard pole beans. That is also an advantage when planting them in three sisters since it gives the pole time to grow.
