Toronto autumn 2021 - how are your plants doing?

Two of my plants that appear to be indica dominant plants are developing a lot of yellow fan leaves.
The two sativa dominant plants are yellowing but not as much.

Here is an example.
I am wondering if I overdid the flowering fertilizer and there is too much phosphorus.

Looks N deficient to me too. Lots of info says high P and K in flower, but she still needs N to make plant mass, and buds are plant mass.

Wouldn't sweat your lower/interior fan leaves going yellow at this stage of the game. I've got that going on here in Maine. You're right not to start throwing a bunch of nitrogen at them, that can throw off their focus on flowering. They're just pulling nutrients from the fan leaves to help build buds. If you want you could feed them a little fish hydrolysate--a mild dose of N isn't going to cause any problems, I checked with a cannabis expert at UVM on that and have used it myself (https://www.fedcoseeds.com/ogs/fish-hydrolysate-8289). It may not make your sugar leaves green back up but if you're worried they don't have enough N to flower well you could add a few tablespoons to their water. I would do it once, 3-4T per gallon.

You feeding plain tap water? Not ph ing your feeds? Using poor quality soil/nutrients. Seems to be the usual problems I hear about.


Ahhhh just read it. Miracle grow. There ya go!
Not maintaining proper ph and using poor quality harsh ass nutrients. You have lockout due to salt buildups and likely an extremely low pH. There's reasons we hate mg.

You can add dolomite lime to stabilize the ph. A little goes a long way in a pot. It it can take some time to start 'working'. This is of coarse if the ph of the medium is low. (Which likely is the prob but I can't say 100% without testing the medium)

One of my plants started doing the same so I freaked out like you did an got bloom boosters that is 6.5-16-15 but then I read something about nutrition block out or something like that and so I stuck a chop stick in the soil and made like 8 holes just to loosen it up and since then she hasnt been getting anymore yellows. And I'm from ontario as well ! Hope everything works out with your grow bro!!

I checked the ph.
When I started the soil ph was about 6.5 but now shows about 7.
The water I use is tap water when rainwater is not available
but the tap water sits in a pail for at least 24 hours before us.

I went to Home Depot and got some of this
but first application I do not see much of a change

@ VolimPicke It could be that - soil lock. Growing in pots can be a bit trickier if you tend to be an over feeder or an under feeder, that's why i grow in the ground (with a good mix of compost), as the ground is more forgiving and self correcting.
If you suspect that you've been feeding the plants a lot, you can try flushing the pots 2-3 times a day for a couple of days to wash out any salts that may have built up.

I'm likely going to try planting a couple in Pots next year (so i can locate them to a sunnier location, as well as bring them into the garage when severe storms hit - i had a severe downpour with hail and tornado-gust winds about two weeks ago, and it just about washed off all the trichomes >:(>:(>:(), and to the main point of this post, I will be using "organic fertilizers exclusively" - fish hydrolusates. I like using Wegmans Liquid Gold (bat guano: 6,6,6), all in a good mix of black earth and leaf compost.

Leaf compost both stabilizes and balances PH levels below 7, which is ideal, so you don't have to worry or F#$%^ with your PH levels for the life of the plant. LC also contains micro nutrients and beneficial root fungus, as well as retains excellent moisture levels without becoming water logged.

I do have an advantage in that i have an elaborate composting system for all my garden plants, and drive around and appropriate about 190+ bags of mainly Maple Tree leaves every late October ;), and then that composts down to about 1 bin of pure black gold. The secret of composting is to turn the pile(s) over every 3-4 weeks to accelerate the process, otherwise it will take 2-3 years to become usable if you just leave the pile untouched. You DO NOT need a big system like mine. You can build a much smaller one just for your cannabis plants. lots of DIY solutions on YouTube.

PS if you would like some instructions on how to build and maintain a compost system I would be glad to help out.

One of many nights :lol:

Sorry to derail the thread…but, for all the MG haters, just wanted to show what a $7 box of dollar store nutes can grow. Salts are salts, people. I don’t give a shit how much you pay or what BS bro science and marketing hype you buy into, MG works. Proof is in the pudding…here’s some pics of of pretty decent pudding, IMO. Pics are 2020 and 2021.013BC5EC-2173-4B2A-B312-5060BD25258D.jpeg7A7E4767-4159-4E85-ACAF-88D376DF9E72.jpeg93E67F26-1B80-4624-9066-17CCCEDBC73C.jpeg

Pics arent loading for some reason. I don't think people hate on miracle grow, just maybe using more of a 15-30-15 fert when you've clearly got an N deficiency doesn't make much sense.
