HPS is not going to result in optimal growth thru genetic potential.

Either grow with MH or CFL's...

Otherwise, be happy with what you have....plants look a tad overwatered.

Anyhow I answered you also on this on another thread.

Let continue with just one of the threads, not both though.

Keep growing.
