dude...Use the bulb you have:thumbsup: ...don't worry about it...enjoy your grow and don't worry so much ...All you can do now is Wait, harvest, dry...Smoke!:smokin:
you can flower with blue or yellow...Although most always recommend 1000w/hortilux/hps...Hortilux blue is a MH BadASS Lamp and alot of growers(those who can afford it) rant about it.
It cost 200 bucks!!!
I have both hps and MH and the MH actually create denser buds than the hps.

Yes, It is generally preferred to have MH/blue, for veg and hps/red-yellow for flower, BUT! Having both red/blue spectrum together is even better. In fact when you look at the spectrum of a Hortilux Blue 1000w MH. It blows all other competitors spectrum graphs away. Period.

I have 2 1000wMH with Agrosun Gold enhanced red spectrum lamps to balance the whole spectrum and give me that combination spectrum I mentioned to you above.

There are so many nice bulbs coming out Now, It is becoming a grower's nightmare...to pick out the best one.

OH...In my 1000w hps, I use Hortilux. Use both your lamps for bigger yield, until you have to remove 400 for veg.
I veg in 2 seperate rooms...I have a 250hps/Master SonT, and a 400 w/Sunmaster MH(same as Agrosun Gold...Made by same co.) hope this helps. latewood

p.s. I always say...Even though Hortilux omits higher lumens...When you start Adding 1000w lamps , whatever kind, whether it be hps or MH; And add another , then another ...you are adding a 1000watts a 'POP'! Don't forget that...peace
