PK boost during flowering?

I've heard that adding a booster of Phosphorus & Potassium (something like PK13/14 from canna) toward the end of flowering can produce fatter buds.

any feedback on this? can it really and is the increase worth the dosh?

oh well I bought some PK13/14 so I guess I'll find out myself.

i used it on my last grow and didnt really notice much. but then again i fed them that at 8 weeks and they went on till bout 12 weeks so i think thats too long. they say the last 2 weeks feed them that dont they!

says to add 3-4 weeks before harvest

I've heard of good results from p&k if used right. I heard its best used around week 5-6. Best of luck with your grow!

Im using PK13/14 i read to use it at the fifth week into flowering. This is advise for my specific strain however. The bottle suggests 3 weeks before harvest or something like that. Ive only just started adding it so cant report on any results. It says to use it with their Canna Boost accelerator for better results and im using both.
