Add a MH light to your HPS as I find that Sativa's LOVE the MH light during flowering

could i add a enviro blue spectrum 250watt or does it need to be a proped mh

If you are running 400 watts or under (probably not) then I would check out Ceramic Metal Halide. It has the spectrum that makes MH and HPS jealous. Sativas are supposed to grow with very tight inter-node spacing and no stretch.

"the ones that dont get full light are fatter than the buds directly under the light."
That means the light is too close. Plants like to move further from the direct light as they get more advanced in flowering.

Even with blue lights, no nutes, and less intense light, some plants will foxtail no matter what you do. Genetics could be your problem. Are there other plants that are stretching and continuing to flower?

Why in the world would someone find and mark this reply as not helpful? The poster specifically asked about Sativa stretch and AFAIK, CMH's are supposed to prevent this. ??
