is this sopose to happen?

Well i transplanted my baby seedlings (about a week old)from soil into a bubbleponic setup. One of the seedlings have very wet feeling leaves, and they are very droppy, is this sopose to happen? or am i doing something wrong? The leaves are a beautiful green.

probably over watered

I get the same effect when I place to much water in my system. it's part of the learning curve. I would also check on your PH levels daily until you get a pattern for water changes.

so i should just take out some water and make sure my ph is around 6.5?
