Looks like a nitrogen deficiency. You want to see that in later flowering but it still has a ways to go. A little nitrogen will help your yields just don't go to strong on it.

What Renfro said...I'd try to add literally just a little bit of Nitro...those plants look good considering they only had a half gallon pot to grow in! But yes, just 8 weeks in you'll more than likely have at the bare minimum 2 weeks to go. I'd much rather have a N def than an N tox at this stage of flowering...so, no biggie.

Thanks for the replys lads, ill add a touch more n and see does the yellowing stop. Ive grown this strain twice before now and they always been a slow finisher, id say at least another 3 weeks to go.

Probably more than that, hard to tell but from the pics I would guess 5 to 6 weeks more.

Yeah ita hard 2 call, the breeder says 8 weeks from seed to harvest but we all know thats lies. The last run i pulled 2 after 10 weeks and i have 1 still going at 13weeks now but i stressed that 1 thats why its slower, maybe another week on it.
