My current grow is going to be at it's 8th week this thursday but i wanted to know the opinions of some of the more experienced growers on how much longer i might have with these.



90% of the pistils across various bud sites on the plants are amber in colour and i need advice on when it would be best to harvest.

Look at the trichs. Google trichrome development or maturation. Read the Knowledge Base. The trichs will change colour from clear to cloudy to (sometimes) amber to brown as the cannibinoids mature and degrade. Read up on it.
