19 weeks in flower ?

It would help if you posted the strain; I assume it is a sativa. Based on some good material I have read (not my own experience, since I have not had this issue)-- Sativas are touchy, and can continue flowering due to continued heavy feeding or high temps. Try cutting back on the nutes, and make sure the ladies are cool and without other environmental stress. You will want to see some leaf yellowing before she gets ripe.

sorry its barnys bluecheese

Ah, I've grown that out (see sig) without trouble-- and I had heat issues. I have been hearing some unkind things about Barney's genetics as of late, and hope it has nothing to do with a botched breeding job. I'd still cut back on the nutes, since you want the plant to stop growing at this point. Good luck.

k ill give it a go see how i get on thanks

ma plant is over ten weeks flowering also m8 ,so i feel it for you , i take it you;ve checked for light leaks ect? ..sativas are a pain in the arse mate you just need more patience.. btw yer plant looks the dogs bollocks

ya its not the best grow room to be honest there are a few leaks have a big sheet of thick black plastic im going to cover the outside with it make it more airtight
hopefully it will raise the temp a little and stop drafts .

yep im pretty impressed with the size of it just wish it was ready and tks for the post

19 weeks? damn. i would go nuts.

the funny part is i have gotten a yield from 1 of its clones that was put in to flower 2 weeks before it
but took 14 weeks
yep its a killer looking at it every day and not seeing signs of it being nearly ready
