First time grower. Should I use 1500W HPS, 1000W MH, or both??

Unfortunately it seems as if everything here (I'm legal in Colorado) is organic which I'm not a big fan of so I'm just going to grow some fire for myself...

I've got nine plants right now, and a few more on the way. They are clones in rockwool approximately 2-3 weeks old (not 100% sure, came from a dispensary). I have them in 1 & 2 gallon pots now because b/c roots were coming through the rockwool.

I have a Sweet Island Skunk, White Rhino, Mad Man Purp, 2 Big Bud, 2 Afgooey, and 2 Grape Ape. They are all under a 1500W HPS currently. I also have a 1000W MH (just need a bulb), should I use this in addition to, or in place of the HPS?? I know the MH resembles the Spring sun with a blue color and is great for vegetative growth, and the HPS resembles the Harvest sun with a red/orange color and is used mostly for flowering. Would it be better to use just the MH, or both for vegetative growth. Seems like it would be better to use both lights because it would put off nearly 2x the lumens.

Also I'm thinking about using a full Humboldt Nutrients line. Anybody have any experience with these? I would be using ALL of the following:

Base Nutrients
- Master A
- Master B

Beneficial Bacteria
- Mayan MicroZyme
- Prozyme

Root Stimulants
- White Widow
- Humboldt Roots
- Myco Madness

Additives
- Verde (growth enhancer)
- SeaCal (calcium supplement)
- SeaMag (magnesium supplement)
- DeuceDeuce (potassium supplement)
- Hum-Bolt (humic acid)
- FlavorFul (refined humic acid)

Supplements
- Humboldt Sticky (foliar agent)
- Big Up Powder(bloom enhancer)
- Ginormous (bloom enhancer)
- Humboldt Honey ES (carbohydrate)
- Royal Flush (flushing agent)
- Structural Integrity (silicate to maximize yield)


In what week should I start giving nutrients?

If you plants fit into a 4x4 area just use the MH for veg - you will not see twice the growth with both lights but you will be paying twice the power.

If you are using a complete pre-done line of nutrients I would recommend following their directions. And to the T.

This might be the right one - they have several feeding charts depending on what nutes you are using.
