Well what you could do and I have heard of a couple friends doing it when there drip system went haywire, they transplanted the plant into a larger pot with dry soil, the dry soil absorbs a lot of water spreading it out.
I know you said you were using 5gal pots which are hefty so that might be difficult, but the plants are small enough that the root system might not be substantial.
Now if its worth it is up to you, the way I look at it is that you have to wait for your other plants to grow anyways so either way you gotta wait. It might not hurt starting another plant on the side though to "replace" it.
I would definitely foliar spray with your algamic though, anything is better than nothing.
