I’m currently using the full canna range Ryzotonic, Cannazym , A+B plus Boost with my girls been in flower I have 5 crammed into a 1x2 2m high tent, Question is when do I add the PK some people say add it twice then other are saying add It in week 5 off flower for a week, Which is tomorrow for me I’ve already mixed it up in my 20L bucket along with all he other nutes.

What’s your thoughts people?

Its not really needed mate, usually causes more harm than good but I would use it week 5-6 at half strength.
I’ve used it at full strength on the canna feeding chart, Light feeding chart I’m following, 30mls to 20L buckets. They are due there first dose at 12 when lights go on, Doesn’t it make buds fatten up? Or is it just needed during the flowering period?

I use Big Bud and give a half dose with extra bloom nutes a week before flipping to 12/12 and stop giving any by the end of week 5 flower. there will be plenty left in the pots by then to see them thru and if the tops need any N, P or K they will steal it from the bottom as all of those are very mobile.

Missing the boat waiting until over half way thru the flowering stage. Ten years in forums and I've never heard of waiting until week 5 before adding bloom boosters. Some say 3 weeks and that's too late as well.

Nooo Nooo buddy I think I have confused you, My fault.

I’ll explain they are in bloom boosters since the day I flipped till 12/12 5 weeks today bang on, Since day one they have been on Canna Boost now I’m about to add the PK 13/14 at 12 when lights go back on I’m just seeking advice because I’ve read around here and another well known forum that others add PK at week 3 for a week then they add it again at week 6 for a week, I’m currently following the Canna light feeding sheduale and it says add the PK in week 5 for a week, Hope I’ve explained it better lol.

LOL jeez, really?! here is just one comment from one of the most respected members on RIU;

PK boost, as in the PK 13/14 started by Canna, is meant to be used when it starts turning flowers into swollen buds, usually around week 6. It's an additive not regular bloom nutes.

**My plants have been on Boost by canna since day one from flipping to 12/12, I Woudnt starve them lol. I was just curious when to add the PK13/14 because peoeple ise it for a week in week 3 in flower or so I’ve read then people use it in week 5 off flower like I have, I’ve just followed the canna feeding chart anyway, Jeeeeeezzz bro I feel like I have been shot out the sky in only asking people’s opinions when to give the PK.

Ah. By week 5 or 6 they should have enough stuff still in the pots to get them thru and like I mentioned they can steal some from the older leaves if they need any more.

There's a big difference when growing in soil compared to soilless or hydro too. A good soil has a lot of stuff built in but the plants only get what we give them with hydro. With good soil there is already a lot of P and K waiting to be used. That's why a lot of experienced organic growers say not to use any bloom boosters at all and grow huge buds without it.

I've done a lot of my own experimentation and just report on what works for me. The buds I grow now are a lot better than the ones I first grew in '78 and I'm sure I'll see more improvements over the next 40 years. ;)

:peace:

Jeeezzz you first grew in 78, Respect man, I bet you have seen the flowers Evolve and Evolve right before your eyes. I’m growing I’m Canna Coco and the full Nutes/Additives, I’ve got a few Blue Cheese some old Scholl White Whidow and a free seed from royal queens which I forgot what is it smells really really hazy though.

We were growing plants outside long before 78 but smoking tops and leaves. Never really got any buds. Didn't have a clue what we were doing.

I got a little grow book called Grow Yer Own Stone by Dr. Alexander Sumach and a Rosenthal book later and with farm dirt, sheep shit and some 5 gal pails grew bagseed in the basement of the house we rented under a bunch of shop lights. Had Thai Stick, Maui Wowie, Jamacian Red Hair and some mexican sativa. Pathetic little buds compared to what we're all growing now but we all loved it. Wasn't until '82 and back in BC that I grew the next plants inside. Got a 1000W MH light and some salts in bags to mix up for nutes. Got fist sized buds off that then life got in the way so it was a while before the next ones. Moved up here to northern Alberta in Feb. 2001 and brought 6 hash plant clones with me. Hasn't been a day since that there isn't pot plants growing in my house.

Started experimenting with DWC in late '01 and have done about 50 tubs with up to 16 plants per tub since then. Mostly growing in soilless ProMix HP with AN nutes now. I don't sell pot so always have lots to share and plenty of choice of what I feel like smoking today. Doing most of my pot in edibles now too as the lungs are shot after 50 years of cigs and pot. All those hot knives back in the day didn't help much either. :D

Wowww I admire your growing i bet you are book off knowledge when it comes to growing, You could probably write a book lol! I’m only 29 and im on my 8/9 grow I think my first one was a shambles, My second one blew me away I didn’t think I could grow such good weed, But I bought all the right things for it like Echothrive 70% Coco 30% Perilite I belive it’s good stuff then I bought all the Canna Products every nutrient and additive and it just took off from there, Ohh yeah I’m growing in Rhizopots to I heard good things about them so I bought 5 16L pots for my tent my tent is 1x2 2M night so you can imagine with it been in 5 1/2 weeks into flower the tent in bulging, The only thing is I wish i defoliated Cos there is a Off leaves and bud sites on the bottom that are not getting no light but I wish I did it in the first week off flower so the plant could concentrate on the top colas but hey hooo you live and learn, Cheers for your reply and knowledge buddy it’s all took on board.

Plus, I bet the weed wasn’t as half as good as it is now than when you where growing outside in 78 and the 80s it’s amzing how this plant has evolved over the years. Thai stick I’ve heard was a very popular strain back then to.

Here’s pics off my plants I’m going to make another thread and put them up in that one properly, Saying how far they are in flower and so on.

The buds I grew in '78 were indoor plants and for the time way better than the mexican dirt pot going around. Lot of good hash in those days too so we did a lot of that. Hot knifing was very popular and you could pass right out with your 2nd big hit. I had iron lungs back then. lol

Today's mongrelized strains really don't impress me much. So much inbreeding and crossing that they all seem the same. I grow mainly for medical effect and if I don't get that from a new strain I'm growing my friends get most of it. Really into CBD strains now and make that into edibles. If I had cash to spare I'd be hunting down and buying some good land race strains but have some decent genetics to play with.

If just getting blazed off your ass is the goal there's plenty can do that but I did 40 years of that and the last decade has been a search for the perfect medical strain for ME! Like a quest for the holy grail I'll tell you what! :D

You should start a journal and don't forget to put a link in your sig so people can find it.

So what where the lights back in 78 when you first grew? I imagine they weren’t as good as they are today?? I would love to see the weed grow back then or the 60s even.

Your right there is loads inbreeding and cross breeding going on with seed banks trying to get the best strain out there mainly coming from the states (I’m in the U.K) Where I live you can get Cali weed at £20 a gram it is lovely lovely weed but £20 a gram is redicoulous. When I first started smoking when I was 14 you could pick a ounce up for £100-120 and it was still decent weed to.

Yeah CBD strains is medical based I’ve never ever grew CBD strains never really bothered with them, Do you mind in me asking how old you are? Where you part off the swinging 60s like the all rolling around in mud with Free speech people stoned to bits.

Talking about CBD strains Royal Queen Seeds have some brilliant strains in thats where I get all my seeds from, Ive never had a problem with them before there a brilliant Swedbank along with Sensi Seeds But I’m not to sure wether they do CBD strains.
