...To the dismay of many cultivators and researchers, Thai strains mature late, flower slowly and ripen unevenly...

(Marijuana Botany, An Advanced Study: The Propagation and Breeding of Distinctive Cannabis by Robert Connell Clarke. p 116.)

If it is an old fashioned Thai, it will want between 12 and 16 wks flowering to mature. A picture would really help distinguish between yellowing that could be considered normal and what may indicate your plant is seriously suffering from a lack of nitrogen and going to turn up her toes.
