ya don't worry about it for now, you don't want to compound that watering issue (i mentioned this in your other thread a minute ago). once they perk up and start reaching for the light, wait ANOTHER few days, then continue your normal watering schedule, but with treating your water. remember it doesn't take much of that pH down to treat a lot of water, so go very little at a time (a drop out of the tip of a straw per gallon, test, repeat as necessary). when you do this, make sure you mix the water REALLY well after applying the pH Down before you test it, it needs to fully dilute and mix into all the water, you don't want it to be unmixed.
i have high hopes that you are going to be turning this around quite quickly. you are already sorting the issue out a lot faster than i did, and even i recovered just fine. oh, and Subb'd =D
