Why only one dose of Canna PK-13/14?
Posted 10 September 2009 - 09:47 AM
My babies (Bubba Kush) just finished their 3rd week of flowering (with PK-13/14) and buds are nicely forming but not massive in size.
Would it be harmful for the plant to be given another dose of PK-13/14 for the 4th week as well?
Does it look like my yield will be decent for being under 250w HPS and only being 3rd week of flowering?

I use PK13/14, and it's the only additive i use along with my flowering nutrients. It says use 2ml per litre of nutrient solution, but when i first gave my plants that dosage, it burned them, i now only give half the dosage (1ml per litre), and my plant are happy with that. Maybe it's because my plants a 8 week flowering plants and the dosage on the bottle is for longer flowering plant like a 12 weeker, i don't know. But if i were you i'd start off with a smaller dose, rather that giving them too high a dose and stress the plants.
Your plants are looking well for 3 weeks into flower, they are not mean to be massive yet, wait til you see them 1 or 2 week before harvest.

I want to know during which of the following stages is the product supposed to be applied:
1. the stretching phase
2. after the stretching phase
3. when flowers (buds) first form
4. when flowers are mostly formed and begin to increase in size
5. when flower size is set and resin production increases
This was the reps response:
I am currently growing two clones of headband that have just begun the second week of flowering. Buds are starting to form. I guess now would be the time to apply the pk13/14. I have a little bit left over pk13/14 from previous grows. After its all tapped out this time around, I'm moving on to ATAMI's BLOOMBASTIC.
"...To begin, there is no such statement on the current label for PK 13/14. The older labels said 5 weeks before harvest which was designed for 8 week flowering crops but removed more than 3 years ago since it caused great confusion with 6, 10, and 12 or more week crops.
I do not know what a stretching period is so here is the best way to use it. First time users should start about 5 - 10 days after the change of photoperiod, about when the first signs of flowers appear, also known as flower induction. Use it for at least 3 weeks. The next several crops, adjust to fit including delaying first application and decreasing the amount of time it is applied. Ultimately you will achieve about a 7 - 12 day window of optimum usage. Longer term crops may require longer app periods (12 days) where as shorter crop response needs less (7 day)It will also save you some money."

13/14 is strong, really strong.
Dont let it burn. Keep thinking about it.
Really 14/14 (NPK)
Canna says the ole usa Or PENNA Dept of Ag wouldnt allow it. Go figure.
What Id like to know is about BOOST.
Does it? Is it worth it? Does anyone have aktual proof?
Works for me!
Canna damns it and calls it an amerikan hippie phenomenon
Despite everything wrong with americuh, whats wrong with us and our foolish ways?
Were all hippies on this bus
Anyone got any ideas on flushing? on BOOST?

Cannabis has been grown for years before these 'Horty Capitalists' cashed up, a smart grower would move to Organics, and appreciate some good smoke
ps why this shit should be posted in 'advanced' is beyond any sensible reasoning....?

i think what a lot of people are forgetting to do when using "any" pk booster, is reducing their base nutes. you can't expect to add more ppm to your regular nutes (at the same strength.) and add on top of that, more ppm without burning your plants. so to safely use a pk booster (LOL, without burning your girls.) reduce base nutes, then add a pk booster...
