Canna A+B feeding

Why do most people growing weed use equal parts of A and B nutrients when Canna clearly thinks we should always put a little more of the latter? Also, did anyone else notice that you can feed very heavy during the initial 12-12 stretch(almost 50% stronger than after buds form). When buds form if I don't cut back on nutrients, I get bad nutrient burn. Maybe because I never give them pure water, just nutes...Input, someone?

1 part A + 2 parts B = Lucas formula. (http://lucasformula.com/) and we are already adding more p and k into our ratio already. for example pk 13/14 and whatever additives you are adding for example big bud, or moab, dry kool bloom, etc. we still need n in our mix, but not too much later on like in weeks 7-8. most of us try to cut nitrogen totally out of the equation.

for me, i dont want to see the bud forming tooo early, i've seen this and induced that stage too early, week 1. although we want to induce budding, we would like the bud sites to stack a few times before going into that bud forming stage. otherwise instead of having colas that are about 5-6 sites long, we are getting colas that are 3-4 sites long. you can feed heavy during that 12-12 stretch, but it's not recommended. it's better to try to stack those sites and try to cut vertical growth and then induce that bud forming stage with more p and k.

also if you are getting nute burn, it's because you are feeding them too much like you are saying. usually we like to stay within 1000ppm the first week, then 1100 the next week. if your plants can handle more then by all means. but if not, that's why you are getting nute burn. do you test out your ppm before watering? do you ph before watering? it kinda sounds like you are relatively new to this. we need more information in order to help u.

Hope i've been helpful! GOOD LUCK!

What medium are you growing in? If your in soil, sounds like your plain over feeding. If your in something like coco your probably not watering till you get enough run-off or your letting the pots get too dry. Coco should be feed everytime you water, and they should be watered AT LEAST once a day in flower. I had issues in coco not watering enough and the same thing would happen to me a few weeks into flower.

  1. I am now at 3ml of A and 4ml of B and 1ml of Cal-Mag per 2L bottle and it reads 750ppm and I feed it at 5.8 to 6.0 pH. I have no PK or bloom boosters, do they make a big diff?

I am growing in 50% canna coco and perlite and water every 36 to 48 hours, I wait for the pots to get to half the weight before watering again.

well atm your ppm seems pretty good, i dont know why u might have nute burn, i would try flushing every week with just ph'd r/o water to flush out any salt buildups. that might be the problem for you. also. adding pk boosters, i would think so. that's just me tho. i use to use canna line as well. adding moab, or big bud. i saw an increase in yield. but if you added more b tho, it could be the same thing. i have read many people saying bloom boosters are not needed. and they are saying that if you know what the plant wants and give it what it needs, that's just as good as giving it the bloom boosters. i can see both ways. i mean since i've only read and heard people say that and have not seen their results. that information is hearsay. and i dont want to lead u down a path of false hopes. i do believe however that if you kinda tweak your ratios and use 1 part A and 2 parts B, that will help in boosing in the p/k and the ratio of n-p-k is more P/K heavy, also adding the p/k 13/14 from canna helps as well.(since using 2 parts B is like using a bloom booster) i have noticed an increase of yield when i did do those things. i however added moab as well. and it helped even more. i saw much more robust buds and a bigger yield. some people do not believe in bloom boosters that is fine. but some people do use them, and see increased yields. when i used lucas on canna, that was imo a waste of money. i shoulda spent that money on GH base, and then bought pk 13/14, and rhizo, etc. cuz when i went to my nute store, they only sold a and b together as a package. thus using lucas formula was kind of a waste. i like the canna line as well, its just i would rather pick and choose other substitues, like for example cannazyme, i would use pondzyme instead. rhizotonic, i would use roots xcel, i just ended up switching to the more best bang for your buck products. and then adding bloom boosters after i figured out what i liked. some strains are different as they respond to different products differently as well. so keep that in mind. what works for me might not work for you. and you might like your results at the moment. so you would have to see what works for u best. now i am starting to ramble... LOL... well yeah just flush every week or use HG's drip clean. if a thorough flush once a week doesnt help your nute burn problems, then just try diluting your nutes even more and longer feeding. the purpose is to give it less nutes and more water to flush out as you feed everyday. longer feedings with a less concentrated nute formula should help do the trick as well. coco tends to lean to salt build up if you dont give it a nice long feed. HOPE I HAVE HELPED GOOD LUCK SIR

I have used AN on 2 grows and I will not be using it no more. The growth and overall vigor from Canna Coco A&B is awesome. The only additive I use now is Humboldt's Golden Tree. I feed my flowering plants 800ppm with 4ml per gallon of HGT. The final ppm settles in around 940.( water is at 140 ) The root growth is unreal, far better than root Excelurator.
I guess it all boils down to personal preference. There are so many nute lineups out there, it boggles the mind. I ditched all other additives and just use the base and hgt and this grow is my best so far.

Peace and Great Grows

I know this is a few years back, but what is the rate of a/b if you're adding 4ml/gal of the HGT?

I have the canna a+b only and I am curious whether the pk 13/14 and Cannaboost is worth running or just get the HGT.
