Description
PK 13-14 is a potent fertilizer additive used alongside your base fertilizers in order to cause explosive growth in your plants’ flowers in your plants’ fattening period. Your buds will end up getting larger, heftier and denser, increasing both the quantity and quality of your yield.
When your plants begin to flower and then move to the fattening period they need an extra dose of phosphorus and potassium, increasing bud size to the point where they look like they’re about to explode. Combine 13-14 with your base fertilizer, whether it’s coco or hydro A+B, during the fattening phase, which is usually from the 4th flowering week onwards. Your Auto Skunk XXL 100% Feminized will grow beautiful with these fertilizers.
Phosphorus and potassium are incredibly important elements when it comes to your plants’ metabolic processes, influencing cell growth and sugar production – they are considered the two essential elements when it comes to producing healthy and potent buds.

Hello, I'd like to get your opinion. Is there any problem using Plagron PK with BioBizz base nutrients? I use Bio-Grow, Bio-Bloom and Delta 9 as a booster. Delta 9 foliar in 3 applications and the last one in watering. Could I use the PK without any issues once I'm done with Delta 9 when flowers are already half-formed? My doubt is because of the origin of each PK 13-14. Organic and mineral. Thanks
Translated from Spanish
Hola, me gustaría saber vuestra opinión. Hay algún problema en usar el pk de plagron con los fertilizantes base de biobizz? Uso biogrow, biobloom y de estimulador delta 9. El delta 9 foliar en 3 aplicaciones y la última en riego. Podria usar el pk sin problema una vez acabado con delta 9 cuando ya haya flores medio formadas? La duda es por el tema de la procedencia de cada Pk 13-14. Organico y mineral. Gracias
