Need Some Help!!! Please!!!

I am 6 weeks into flower. everything has gone pretty good so far. I went in and looked at the girl today and the top leaves have started to turn yellow and it seems that the plant is less sticky and has no smell anymore. Anyone able to help me?

Oh No! Aliens must have probed your plant, call the FBI!!

Some yellowing can be 'normal' during late flowering.
You should offer some photos & details (e.g., grow medium, nutes, etc.). You may want to post this in the Plant Problems forum.

How close r they to the light? Its possible they're getting burnt from the light but hard to really help u without pictures...
