Hi I would be grateful for any help, I have seen a few topics on this but none seem to reach a conclusion.

I have a canna leaflet which says to add pk 13/14 at the start of week 3 when small fruit is developing but others say that on the bottle it says to add 3 weeks before the end of flowering.

which way should it be added, and is there any problem with adding it at both times?

Thanks for any help.

You should do what the bottle says to avoid any problems.

You should try. Maybe you wont run into any problems.

The bottle is in Dutch.

The leaflet I have is Canna branded and downloaded form the place I bought the bottle from and says add at week 3 for 1 week only but the the canna usa website says to add 3 weeks from the end, it's inconclusive.

Hey

thanks for that grow schedule, would that apply if your not using coco though? the canna leaflet I had said to add 25Ml/100L on week 3 only which is 2.5Ml/L compared to that grow schedule which recommended 1Ml/L

Anyone got anything else to add?

use on the 5th-6th week of flower at 1-2ml per lt for ONE week only. easy

thats real good on a 6 week strain?????

on the bottle is says add 3 weeks before end of flowering, can't remember is it says only add once or not

yeah 3 weeks before flowering would of been an easier way to put it, sorry for the confusion.. on the bottle reads "use for one week only. Due to pk13-14 being pharmaceutical grade never use for more than one week!"....
