Harvest Time Question

I have been flowering for 6 weeks with some bagseed (But they appear to be mostly indica.) I am starting to see some amber hairs. Should I switch to plain water now for two weeks? Or does bagseed always take 10 or 11 weeks to flower? It was some really good bagweed the seeds came out of.

Sorry my cam won't pick up the amber hairs....

I'd give it at least 8 weeks to flower, if about half of the hairs are amber, pick it.

Maybe this will help
