Buddah Haze not budding NEED HELP please!!!

Im growing two different plants in my grow room, a "La Cheese" and a "Buddah Haze". Im using a hydrophonic system and a 400w hps bulb, curently there in the fifth week of flowering, the La Cheese is budding beautifully, I could see buds from the start off the third week of flowering but no sign of the Buddah Haze,what could be the problem??

Can we have a normal light close up of the top?.freakin sativas can take forever it seems.

That plant doesn't look right.

I'd say Coho has it right: sativas can take a lot longer to start showing flowers. I learned the hard way about Haze's trying to finish them outdoors. You gotta be patient with them, especially some of more sativa-phenos. Also, careful what you feed a sativa dominant plant. They don't like too much nutes, and the ph can't be that high, where an indica-dom barely seems to care. Get your ph in the 6.5 range for the Haze.

as long as your sure its a female then its just a matter of patience my friend. it will do its thing but you need to give it time.
