you can find some good info on the above toolbar click on grow room , then the first choice "how to grow..... "
hope it helps . from what i am seeing ..... it should not be long ...... you are looking for a slightly amber color....... but read the info on that link .... you may have to cut and paste into your browser ......
They look like they are getting near harvest date depending on what percentage of amber your shooting for. I would say your currently at mostly milky with a couple amber. Most shoot for 20-40% depending on whether your looking for more of a cerebral or body high. Give them about another week or two but keep an eye on them daily.
