NEED EXPERT ADVICE!! PLEASE HELP

Hey everyone this is my first time posting so I hipe i get some decent feedback.

I was wondering if any experienced growers can give me an idea of how much to expect to harvest on this first grow.

I'm really trying to stay away opinions or guesses. Im really hoping to get some educated guesses from experienced growers. I'll try to be as detailed as possible.

The Strain: Dr. Atomic Blueberry Jam (NL#5/Blueberry)

Setup/Equipment:

Sealed Room- 9 feet Long, 5 feet wide, 8 feet high

2 - 1000w HPS lights
2 - Sunsystem Air Cooled hoods with glass lenses
1 - 10" vortex fan rated @ 796 cfm (Exhaust fan)
1 - 30x16 Active Air Carbon Filter rated @ 300-600 cfm
1 - 6" Tjernland duct fan rated @ 541 cfm (Intake Fan)
1 - 5,000 BTU Air Conditioner

Room Temp Range: 74-81 deg F. lights on / 69-73 F night)

Nutrients/Grow Mediums:

-R/O, UV Treated H2O
-50% Cocoa Canna / 50% Perlite Mix
-General Hydroponics Grow/Micro/Bloom (Drain to waste program)
-Floralicious Plus
-Cal/Mag supplement

Feeding:

Moms in 3 gallon pots get 1 gallon nutrients every 2-3 days
with a flushing on every 3rd watering. (Hand Fed)

Clones in 1 gallon pots get a 1/2 gallon nutrients every 2-3 days
with a flushing on every 3rd watering. (Hand Fed)

The details:

3 mothers from seed, 3 1/2 weeks into flowering, standing at 38" tall.
They were vegged until 30" then put into flowering.

7 clones from mothers, 31/2 weeeks into flowering, standing at 15" tall.
They were vegged until 12" then put into flowering.

Both the mothers and clones are not lanky at all and have tight internodal spacing. Not sure if this is going to affect light penetration, even with the 1000w lights

The Questions

1. How much should I expect to see at harvest time?? (ballpark figure)
2. Any suggestions, tips for improvement on room setup, nutrients, would be much appreciated.

Thanks everyone,

Sincerely
Dr. greenthumbs
