You say the seedlings are in rockwool cubes.

What are the rockwool cubes in?
And they need food now.

 

Id Try Ebay there are alot of hydroponics shops on ebay just a search 4 that, there you should be able to find all the food your plant needs...

 

i put the rockwool cubes in the soil i see roods comeing out from the side of the rockwool cubes so i tink that is the best that i make like this
but the leaves start come withYellow leaf edges
