well you can never have enough light really till you got your own sun going, but then you got some really serious heat issue
be glad the it isn't shottin up like a rocket, that would be what we call stretchin then and that is a bad thing to have

Hey buddy, you need to tell us more, like how far is the light from your babies, what medium are they planted in, how often do you water? Nutes?

that dual spec HPS you got ain't a bad thing by the way, fancy for sure to have, but is isn't the optima way to go really, you know. it can be too hot for the young seedlings, it ain't really in the spec for veg nor is it in the spec for flower too well either.
vegging can be done just great with a few CFLs in cool white spec, no heat issues and if you not veg till they get giants they will just do fine. for flower the simplest HPS do just fine and the go for half the price as a dual spec does. that doesn't implies that you have to kick it out really but if it is used up you won't have to get the same again, rather go for a bit cheaper normal one

so far no S-O-S

well, ain't too tall, that is true... i would blame it on the light spec of the HPS, it is the same phenomenon i know from growers that used 2700K CFLs for growing in veg instead of 6500K
so since hps are rather in the 2000's K spec this could be the cause for it. humidity should be the trouble fact since you got large soil surfaces you water every day paired with a big hps and its heat.

well that would be a option, but for your ballast you will need a conversion bulb that can be fired up by a HPS ballast... and that doesn't works with every blast sys and is freakin expansive too. for the same money you would get a smaller 400W MH probably

85F is a bit hot but not to far out of range... a bit ventilation would harm but it won't kill them all right away

okay, do that, even if a few cheap CFLs would do the trick too and could later on be still used around your place

Well technically you can use that HPS system for your entire grow, but it really won't show its true colors until flowering when the plants are more interested in the red/orangey spectrum. But that bad boy is bright enough, so I don't see why it shouldn't work. Yea I would definitely add some CFLs for side lighting just to be safe. Good luck!
