I understand that with the PK 13/14 you are to use it 3 weeks before harvesting but when you say once do you literally mean only once? Is this correct or do you use PK 13/14 once a week for 3 weeks?

You would use PK 13/14 during weeks 5, 6 &7 of flowering at 0.5-1.5 ml per litre.
hi guys, thanks for taking the time, can you please tell me how to use canna pk 13/14 as i am getting confused with the dosage info, i am growing with the amazon 32 and it usually has 30 litres of water at all times it is around another 2wks until ready for the pk, thanks for that. here is another one for you. my plants in the amazon are now around 2ft tall at this stage and just starting to show flower but they are all over the place certainly not standing up proud like they should but really good looking plants,when i was growing in soil there was no problem when they got heavy i just tied a cane to them and they did good but am a lot concerned about how to keep them upright and as you can imagine when the plants are leaning over so much the nutrient solution is escaping out of there small pots. anyway thanks a lot for your assistance with this and look forward to hearing from you. thank you and all the best.

We would recommend using the PK13/14 in weeks 5, 6 & 7 of flowering at 0.5 - 1.5 ml per litre. With regards to your plants leaning in the Amazon system, we would recommend using yo yo plant supports and/or crop support netting. If used correctly, these support devices can take some of the weight of the plants which will struggle to naturally support themselves in a minimal media system such as the amazon.
