i recently bought some pk13-14 for my skunk 11 plants. i would like peoples views on some advice given buy a guy in the growshop. as skunk 11 takes about 11 weeks to flower (and so as not to mature the buds too early), i was told to add pk13-14 to my nutes about 4-5 weeks from cropping for 2 weeks rather than the recomended 1 week on the back of the pk13-14 instructions (would this 1 week of use apply to quicker flowering indicas?).

hi mate, I've grown sk11 before and left the pk nutes in for 2 weeks by act of lazyness, but it was 3 weeks from finishing time. They put on a nice weight to the buds but started bolting (growin new buds offa the old ones) which is ok. the pk 13/14 I used the instructions said to use 3 weeks before croppin, but i've also used it in soil for 4 weeks ending 2 weeks before croppin at 15ml per 5 ltr with good results. Hope thats helpful.

Canna have now revised there instructions on when to aply PK 13-14. It used to be 3 weeks before harvest or week 5 on an 8 week flowerer. Now the new instructions are to aply it for about 6 days at 1.5ml per litre of nute/water at week 3 of bloom, so 3 weeks into 12/12. Or when the initial strech finishs around the 3rd week aply it for around 6 days. The reason I know is I only bought some for the first time and posted a question here on uk420. If you go to the Canna web site and check the feed planners they have it will give you the full instructions. Hope that helps you mate
Ooops just remembered its an 11 weeker, id say aply it when it finishes the main stretching at the start of 12/12, and just aply it for 6 days whenever she stops strechin. The reason Canna chanhged it is cause its to help development of buds so aplying it 3 weeks before harvest means the buds are almost finished developing so it doesnt maximise pk's potential

Cheers for that jiveturkey, gonne try new regime with pk and warlock and see how they do

! cheers for the advice, thats sort of what i was thinking, got about 5 weeks left so gonna add it now rather than leave it too late...might leave it in for 2weeks too
