Canna's Grow Thread

I hope so too. Should prove to be a pretty decent harvest if everything goes well but environmental is a little whacky. Been getting a lot of rain and well below average temps. Humidity inside is sticking around 67% right now and temps are hovering around 69-70°F. Had to plug the heater back in! Its 59°F when the average temps for this time of year are the mid 80s

So I was gonna make another small update about how the rising humidity in my area is stalling out transpiration and started causing calcium issues. But after having the heater on and setting the thermostat a little higher so it runs a little longer has changed things for the better! I think that dry hot air being passively sucked in through the bottom passively vents and up through the plant has opened up the stomata and got transpiration flowing again, so much so that I may have to water before lights out today. The pot was very heavy this morning but its gotten a lot lighter throughout the day and all those leaves on the very top that had yellow centers and green edges have COMPLETELY greened up in just a matter of hours after turning up the thermostat. There is a couple leaves with some very minor rust spots but Im glad I got her drinking steadily again.

I didnt take a pic this morning but they were much less green this morning, and as you can see she is is now touching all 4 walls and just the back left corner has the most empty space. But its insignificant. I cant believe how much she turned around in half a day. Also the smell has amplified, there is a nice somewhat strong chem/gas odor with a little skunk mixed in.

:bison: wow Canna’, she’s a beast! Let’s hope she’s not a huge stretcher during bloom :sweat_smile:

Yeah, I think cool T’s/poor transpiration mucked up the VPD, and the higher pH water also magnified the issue too… cool T’s mess with uptake, P and micro’s (like Fe) are especially affected, plus Fe gets real bitchy at higher pH’s… you steered out of a forming perfect storm :sweat_smile:

I dig the tent spreaders mate :star_struck: – I see a million $ patent in there :grin:

…can’t wait to see this girl in bloom, the stank is going to be epic too!

She’s almost done actually. Ill upload a picture tomorrow but shes done stacking and definitely flipping to flower production.

As promised

You can see that its starting to really slow down. Also did my week 3 clean up a hair early. Only lollipopped. I took a lot off and Ill take care of the fan leaves that shade out some lowers. Pics popped up in the wrong order. Oh and I turned my light up another 10% sp now its at 70% about 18" away maybe a little less.

Also a little off topic but I was out fishing today and broke my St Croix Mojo Bass Extra Heavy rod for frogging and punching. Now I may have to sell some when its finished and buy a new one. $230 gone :tired_face:

This defoliation and tucking is proving to be a pain. My back is starting to hurt :laughing: and Ive only been at it for like 15 mins.

Alright I was lazy so I didnt finish the post yesterday. Dropped the net because ive got a lot of very thin stems and once weight hits them they will definitely flop.

Here she is after the defoliation tucking and lollopop

Well its time for the official update now.

She’s drinking like crazy, but thats to be expected when she starts pumping out flowers. Its gotten to almost 2 gallons per day with very little runoff.

Since saturday I have done my last topdressing with craft blend. I didnt go too heavy on it though, about 10 tblsp. I also layer on some buildaflower and watered that all in with a fresh inoculation of rootwise microbes and a modest half dose of buildabloom, so she should be all set up for some heavy feeding during flower.

Besides that like I said in my other post my light is at 70% and as high as it can be in the tent right now. I think thats probably as high as I will crank it to be honest. My environment is holding pretty stable at around 75-78°F and my humidity is kind of been a pain the lowest Ive seen it is around 52% but thats usually right when she NEEDS water but sometimes I see it hit 63% after a watering but usually hovers 56-58% which is ok. Theres plenty of airflow. She is starting to get a little more yellow at the very tops again but Im just gonna ride out the next couple of weeks and she how she responds to the food and microbes.

Just thought Id share a quick update before I forget. I dropped the light back to 60% as the yellowing seemed to get a little worse when I did that. Also strapped my carbon filter to the side bar on the roof, let me get the room to raise my light as high as it goes. Its about 24 inches from the canopy, but she doesnt seem to respond well to higher light intensity

Looking very heathy nice work you’re going to be rewarded!

I sure hope so. Trichomes are starting to form now and the smell is starting to become very sweet.

So Im having definite ph issues in rootzone again but shes still chugging along.

Some rust spots a few nodes down from the very tops are forming on the leaves directly under the center of the light. Im pretty sure its just slightly too high. My new ph probe tip and calibration fluid are a few stops away on the Amazon van right now, and bought GH Ph Down which comes tomorrow. I wanted to go with phosphoric acid rather than citric acid because its more stable and microbes wont break it down as easily as they do with citric acid. Its not technically organic but Im using it anyway.

Im thinking that the slightly high rootzone ph and the light are forcing the plant to work harder than it can take up nutrients, so with everything I need to manage the ph better hopefully we see a somewhat immediate turn around starting wed/Thursday.

Here’s what she looks like now, not horrible but not too great either. If you zoom in you can see the rust spots and interveinal chlorosis and general yellowing I was talking about where as the edges seem to be more ok. Lights at 50% and hanging as high as possible till I see some recovery.

Edit: probe came, soaked with kcl solution and calibrated.

So just an update for this post. Of course I had to water today and the ph down isnt coming till 9pm at the latest. I really wish I had actual hydroponics/gardening stores here in Wi. We do have a few but they are all ao far from me its just a hassle, and I think in the whole state there are 2 actually legit hydro stores. I really wish Amazon fulfillment centers in WI would start carrying indoor gardening stuff.

She looks quite nice though mate! Well done :wink:
Pretty bush, just a few minor things, but you are on it so, hope you got that killer pheno! :hugs:

So my ph down came yesterday, and I watered today with water at about 6.3ph. I went a little overboard though. I ended up filling my watering can which is about 2 gallons so I could actually get my ph tester in the water and still see the readout, I poured slow over like 40 minutes but right when I finished it started running off, and is still running off, id probably say 15-20% of the total. Hopefully that didnt upset anything in the root zone but she wont need water for a bit :sweat_smile:

Took some pics so yall can see just where she is sitting and hopefully watering with the correct ph going in will help steer this girl in the right direction. Smell in the tent is just as sweet as gassy. Its very pleasant.

Like I said she isnt horrible, but she aint great either. Bumped the light back up 10% and will be going up to 70% by the end of the week as long as things look like they are stabilizing.

Just thought Id share a little update (forgot pics)

Seems like things are stabilizing now a bit with watering with ph corrected water. The tops did get worse than the last pics I uploaded but today was the first day I didnt really see any of the chlorosis or rust spots spreading. It also seems like the green parts of the leaves are getting darker which must mean that nutrients are starting to become available again.

Watering daily with 1-2gallons depending on weight of the pot, and trying to stay in that 6.2-6.4ph range.

One thing I gotta note is that Im NEVER going back to a citric acid ph down. Phosphoric acid is much MUCH easier to use. I never have to guess how much to add, I ph the start and its usually about 5/8ths of a tsp to get it to that range where as when I was using FF ph down every day it was different.
