1000W ballast and 600W bulb is a no go sir. The bulb must match the ballast...must.

Are those bags in the pots?
Have you provided adequate drainage?
If all the dirt is contained in the bag you could pull the whole bag out, cut holes into the buckets, fill up enough soil, cut the bottom of bag and let it all drop out the bottom back into the bucket and it should come up to the right height.

Alternatively pull up the bags and put something in there like other smaller pots upside down to bring it up to height.
