Hi all,
Its my experience that you'll probably be better off to go ahead as mentioned with the seeds germinating and you'll probably end up using them.
I read a contradiction which is that there was mention of too much water and then .... not enough. I doubt you'll come away a winner if you try to cure both of those problems
... so pick a direction and dr towards it.
I can tell you that pot prefers not enough to too much. What it really likes is to be flushed with water twice a day and then left dry the rest of the time.
How often do you water? Memory should suffice to tell ... was the soil often very dry when you watered or was it still moist (under the top crust) and you went ahead and watered it anyway.
A good rule of thumb is if you return to water and the soil is still moist from the last time ... you should probably back off a bit.
It also depends on the soil as to how often to water. Some soils will retain moisture better than others.
I agree once potting soil dries out it can be difficult to get it back to original shape.

variables:
any chance you watered with a container that was tainted?
Do you have enough light to support a plant once it starts out of infancy? (I couldn't tell)
Do you have the proper spectrums .. I think its blue for new and red for dead (meaning you're on the last part of the growing process)
The plants the way they are drooped over ... make me think its too much water. The reason I think that is if they were drooped from lack of water then the watering you gave them in the picture should have been very adequate to have perked them up and they perk up in a very short amount of time if the reason for drooping is truly lack of water.
Too much on the other hand can be devasting. Plants can seem to go into a stall and just never really seem to come out of it ... not in comparison to if you went ahead and started with new crop. In other words you can spend more time trying to save the plants than if you started over with something you know isn't diseased, or I guess they could just be depressed. Maybe they've seen too much of Jack Black in his tighty-whities lately. I know it always depresses me.
Looking at the soil it does look dry. Its pretty easy to tell. just stick your fingers down in there and root around a bit. if you come out with moisture/moist soil on your hands then its getting wet enough.
growing inside I would suggest setting up a watering plan and then sticking to it with making only slight adjustments as you go along.
