I am assuming english is not his first language give him a break. here i will translate in to grower speak.
"I germinated the seed on 8/13/14, she is not about 1 meter in height, I think the plants yield will be enormous and I have fallen in love with the strain. Has anyone had experience in growing this strain if so how long did you let it go before chopping?"
No I have not grown the strain, if it is a super auto then it is not unheard of for them to go 90 days. See what the seed bank website says, and check the trichromes 1 week prior to that date. In my opinion harvest time varies for growers dependant on how they like their smoke. No one can answer that question for you IMO.
Give him a break? I was simply pointing out that this is how the RIU old timers get bad press on the 'net. I didn't light him up or hurt him. I merely laughed my very high ass off. Now that I'm not high (yet) here's how he can get real help. Because it looks like there's something wrong with those plants but I can't really tell because of the HPS.
So OP here's what you need to post to get quality help on your grow.
(1) Give images under metal halide, cfl or incandescent (no hps).
(2) Give complete synopsis in one post telling us all the details.
(a) substrate
(b) nutrients
(c) additives
(d) age
(e) strain
(f) environment (specifics on temperature swings, images of habitat, ducting, humdity, etc...)
(g) miscellaneous
Now you will have a chance of getting meaningful support because most people here would like to help you. Unfortunately without this info all we are doing is guessing. If you decide to use the wrong guess you may end up potless.
