No matter how long the strain ,I add at week 5 of Flower .then just canna A/b for the rest of the time.
Thats what ive read that around week 5 for a week then continue with reg nutes till flush.. just wanted some opinions from other growers that have used rather than some feed chart from the canna site although i understand that it will be set out that way for a reason apart from having slightly high dosages. Thanks for the help/advice guys!

Now this is my first grow in years and biggest one yet, i am still young and have much to learn but heres a pic i took a couple days ago just want your opinions... i know a couple plants are a out of proportion from the rest in height...(i know) the conopy is un even, thats why a couple lights are a higher than the other, also there are three different strains in here too i know its not the perfect looking crop but this is what ive got

best time to use it? How many ml per ltr ir gallon? How long to use for? Has anyone used canna’s pk 13/14 before, how well did it work?
Ok heres some Master Grower Truth, Marijuana will Drink Nutrients All Day Every Day in the Flowering Process, At week 2 of flower you can hit the plants with a small dose of Potash+ or PK 13/14 of any sort (any brand) and the plants will use it, ive used it in small doses nearly every feeding and still had great success, Best time to use it is once a week every week of its flowering stage, Weeks 3 to 6 are very important as its the most bud growth

You can also use a product or of the like called HumiBoost by Hygen, it increases plants uptake of nutrients amazingly, and always use a Silica and a CalMag if your nutrients dont have enough of it, A Master Jedi Grower once told me Max Oxygen is the key to dank buds, you want all the worlds air in around your plants, All the Air

Yeah i feed and water every day but use a bit less than half the recommeneded dosage, problem is my nutes are set out to feed from veg to flower so has quite alot of N in it and not too much pk so i tend do drop that even lower and add pk to my mix or feed seperately. How important is nitrogen during flowering?
Nitrogen is only important up until weeks 4 or 5, the plan is to keep them on veg nutes and cut it down and out slowly from the very beginning of flower until about week 4 of flower or abit longer if yellowing keeps happening, and then just rely on the small amount of Nitrogen from the CalMag Product for the rest of the grow

The real question is on what week finisher. Week 5 of 12 week or 9 week finisher or ?
That's why I mentioned clones earlier. Its handy to know the time line.
Tbh unless its full hydroponics, in coco you domt really need a finisher, you feed nutrients and boosters until they are almost finished and then the flush of fresh water is the finisher, the plant will finish itself, a finisher product is normally designed to flush out any and all other nutrients of the same brand out of the plant

So basically try cut back most if not all nitrogen by week 4/5 and then just calmag and pk?

So would you say use it once a week and then around week 5 for a full week and then cut it out or give it once a week untill im ready to flush or?

That sounds like a great way of using it yeah, as long as your comfortable with the results, obviously if we over feed we can get lockouts like too much potassium causing nitrogen lockout etc

Although the dude is trying to be helpful. I would ignore that advice.
We are talking about canna line nutrients which as you know and obviously he doesn't is a part a and b which is the same from veg to flower. cutting out nitrogen will mean cutting out all other nutrients including all the micro nutrients that are needed . Just using a PK booster and cal mag half way through flowering will not serve you well.

The confusion with the pk13/14 is that the bottle will say one thing and the online chart another and both can be wrong because every strain is different and will also behave different from one environment to another so there is no exact time for every situation.

Try just using 1/4 dose starting earlier and running it longer, you can always up the ratio if you feel it needs it.

Keep em green. Don't overfeed, don't starve the plants, don't flush.

I put the size of the Buds i grow down to the Big Bud and Pk combo along with good light and tlc.

Use for one week thats all that is needed,You still need to continue using a/b nutes right through veg and flower

Dude Check my Journals out ,Been using coco and canna a/b with canna boost and pk 13/14 for years ,but swopped over to big bud after around 3/4 years .and i get same weights,if not more than my friends who use all the canna line.But you need to still use canna a/b along with pk 13/14 also big bud ,Right through till the end .But big bud from weeks 2/4 then canna a/b then pk 13/14 for a week then just canna a/b,till the flush.Its the reason i love the stuff one nutes, apart from the pk spikes all the way through.And i have also used in in soil ,all my plants are started in soil ,i feed them canna a/b,and they love it never had no problems,only for a few week 3 at most ,till they go into auto pots/Then i move over to 60/40,coco and clay balls or larva rock
