Best way to use pk13/14

Hi guys. I'm a week in to flower so will be ready to use the pk13/14 soon. I've read a couple different ways to use it but was wondering if anyone knows the best way. Canna recommend using 1.5ml per litre in the 3rd week of flowering. I've also read you can trickle feed (0.33ml per litre) from start of flower all the way through to harvest, which I started doing yesterday. I would love other people's opinions on this. Cheers!

When the plants are in stretch, until they are done stretching, about 2 weeks.

This is what the buds looked like the day I started the 13/14.( it is used to assist in setting bud sites, so it needs to be used as the buds set...but not until.)

Hi Jeepster. Thanks for the reply. I get what you're saying completely. I noticed flowers about 5 days before I started trickle feeding the 13/14 (2.5ml to 8 litres) the day after, they seemed to explode! Ive fed them twice by mixing the 13/14 with my regular nutes. D'you think this is a safe way to administer the 13/14? I've tried adding pics but my Internet is down and I'm relying on 4g right now.

Its used when your buds are ready to grow out, as in they have formed and are ready to grow in girth. There is no set week to do that because all strains differ. Could be week 5 could be week 3 not including stretch time. If your not sure about your strain then start earlier at lower dose and use longer cutting it back down. All it is is P and K given at the time your plant wants it. You can grow without it. But its best used with the rest of the canna range since that range is balanced to have it as part of the system. Although there isn't much difference between one bottled nutrient and another.
Nip over to the official Canna thread and see what everyone else thinks.

A lot of experienced growers know the only real world difference between grow and bloom foods is the N-P-K ratio so just give Grow all through bloom but add PK 13-14 at half dosage to synthesize bloom food in flowering.

Hi Corey, thanks for the reply.

Hi budman. Thanks dude. I think this is what ive been doing. Just needed clarification. Been giving 15 ml a and b of the canna range per 8 litres plus the last couple days I've been adding 2.5ml of 13/14. Was gonna feed the same ratio right up until flush. D'you think that'll be ok? Or should I follow the bottle?

Start of 2nd week of adding13/14PK. Start of 4th week of 12/12.
Most likely will be the last. Bud sites are forming nicely.
Blue Fire. I suspect...she will be a heavy girl.

I would drop the dosage to at least half the last week but its your call.

So, keep doing what I'm doing until last week before flush, then half the dosage? I added a couple pics. They're 15 days in to flip and 6 days in to flower. I've only read of one other person to drip feed the 13/14 like I'm doing but as you can tell by the pics, the plants seem to love it.

Ita a proven fact that Cannabis needs very little P even in flower, crazy ratios like 15-55-45 are just asking for trouble, less is more with everything in growing (except the final yield off course lol)

Am done using the 13/14PK. Stopped last week. That was like 16 days where I used 13/14.
Still using the Canna boost, used it with the 13/14, and will continue until flush. And still of course, using the Canna A and B aqua flora.

So this is where they are.
Good bud sites and these are most likely going to be fat girls.
The boost is supposed to increase flavor and smell terps. We will see???

This is 32 days from flip.

Sup Jeepster! looking good my friend. I'm gonna start the pk13/14 in 10 days for a week, then im gonna use ripen by GH for 10 days, and finish off with florakleen for the last 5. Really wanted to get the canna boost but its oh so pricey. The girls are already pretty beast though and i still have 4 weeks left til chop so im hoping it wont matter so much.

Those look sweet.

The Canna boost is sooo pricey. But from all reports I have gotten...money well spent. I figure I will use a third of a bottle per cycle, so that spreads out the cost a bit..
