Now for some input.

What I think is happening is your plants have been over watered from the rain. First is what is the natural soil? If it is clay or some non-absorbant type of soil. What happens during a rain is the hole you made for the plant and replaced the natural soil with good soil acts like a bucket and holds the water for days, this can drown the roots. There is nothing you can do at this point to help them except prey they come thru. Judging by their size you should be fine because they will eventualy absorb the water and just stunt there growth a little untill they recover.

Just keep in mind for your next grow try finding a spot that is higher than the ground around it so water flows slowly away from your plants, if you place them in an area that is lower then all the runnoff will accumulate in the hole you dug causing a situation your in now.
