looks like your Girl needs more Soil or Nutes. I'd guess the light color is due to a potassium deficiency. if you can't afford nutes, make sure She has allot of soil to feed from. Transplant it soon. Adding liquid nutes during Flowering can greatly increase your yield. It also depends on the quality of soil you Give her. If you give her Great soil, She will do better without Nutes. If your soil is lacking sufficient quantities of certain nutrients, Your Girl's growth could be seriously effected.
