Leaves canoeing down and up? Doesn't seem like n toxicity.

Hey I just joined, call me a noob whatever you want haha, I normally don't even ask questions but figured I'd give u guys a try since I read your site a lot.

I have a few different strains going in a few different soils. The plants in question are bag seed in ffof soil, 5 gal smart pots, I started feeding them 1 week before 12/12 with the fox farm trio diluted to half recommended, switched to flower nute schedule a week in.

Plants are about 4 ft tall and other than the canoeing, there's nothing else wrong that I can see and growth is fine. I don't measure ph never have, I have considered it but I would need to order out as I live in a rural area and have never had problems in the past.

My other girls are fine with the exception of my white widow seed girl who had n deficiency and is coming back strong after feeding the last few times, she's in mg soil so not much help there. I feed twice a week every other watering and have never flushed my plants. I usually feed half a gallon or a little under to each plant and water the same.

I don't think it's the light but it's a 600 hps and the plant affected most is the closest at about 24 in or so (haven't measured) if that means anything. I've read a lot about canoeing and it's conflicting, it doesn't look like n toxicity. Photos are of the canoeing and showing most fan leaves are regular and not very dark. I have other plants in the room much darker doing better but they are different strains. I'm assuming genetics. Not sure though.

Any ideas? Thanks in advance.

as this is a bag seed grow

you really don't know what to expect

differing grow rates, differing strains needing different nutes etc

by the pics there is definitely a strong sativa in that bunch

you can expect her to get big!

canoing leaves is a temp control issue

more so under an hps light

ensure you have a small fan in there on the plants

as well as an extract fan

see the enclosed chart for the best height in inches


Mg soil is crap...don't cut yourself of at the knees by going cheap

fox farm ocean forest with 25% perlite is the best

good luck

heat problems close to the light and a bit over watered

Ok so I have a decent size oscillating fan going across the canopy back and forth, my hps is as high as it can get (no pun intended) and I'm not using a vented hood.

As for air circulation, I have a 4 in intake fan with a filter attached, the fan draws cold filtered air from under my house when the room (4x4x gets around 78 degrees or so on a thermostat, it's set up automatic and comes on once every 10 or so mins. The room is small enough that it creates a pressure and forces air out two 4inch vents on top of my room.

When the light is off the room gets down to about 67-69 degrees f and when on it stays around 75-79. The plant in question mostly is the closest to the intake fan, when you say canoeing is from temp, is that just a general thing or meaning too high or low?... Maybe not steady enough?

Other than the pressure forcing air out the room has no extraction fan, it hasn't been a problem untill now, can this be doing it?

At the moment the plants are actually getting ready to be fed/watered. I let my plants dry always between and that's what makes my schedule. I even let them slightly droop sometimes before I water and they seem to like it. I don't think it's overwatering but thanks very much for your opinion. It very well may be that the light is too close, just no signs of stress on fan leaves only new growth on bud leaves.

Also I didn't go cheap, I use mg soil for my houseplants, I have for years. When a friend gave me a couple plants to start, that's what I had lying around so instead of letting them die I just used what I had left of my bag and made do.

Awhile later I was able to obtain a bag of ffof, that's what this plant is in, just straight ffof. Since then I have bought more and mixed a small bag of black gold perlite and a cup of hydrated lime in with each bag. I haven't used this mix but it will be for my future girls. Thanks again guys for the fast responses! Any more info is appreciated.

Thanks a lot, this is def an issue as I don't have and air exchange during lights off. I'm getting it sorted out but as I said before I live in a remote area so it takes time.

I kept on my feeding schedule and after that it seemed like maybe it was possibly a nitrogen problem all along or at least contributing, the fan leaves tips started to claw down but the leaves weren't very dark green. Anyway I went ahead and flushed, so If it was I'm assuming it's a genetic thing making the plant more prone to n. toxicity, does that sound plausible?

Since I had never flushed my plants in this room before I had to figure out how to get multiple gallons through them without flooding my room since it's so small. Yea right.... so I ended up taking them one at a time out and into my shower/bath and running a good five gallons or so through each one.

Then I figured something out that may already be known.... it could be a cool new trick, maybe not. I noticed the smart pot was taking forever to drain and I wanted to get the other plant going so I set the first one on a five gallon bucket. Because a bucket is tapered and the smart pot isn't it fits perfectly in the first 6 inches and makes an airtight seal around the sides.

When I first put the pot onto the bucket while it was sinking in I noticed that it stopped draining untill the pot settled in the bucket then continued on. About 15 mins later it stopped dripping and I went to pull it out and get her back under light and that's when it happened. The seal was so good when I pulled the smart pot up and held the bucket down, it sucked air through the top of the pot and douched out a bunch of water out the bottom and into the bucket. I've always been told air is great for roots and it definately pulled air through.

Anyone have any thoughts on this? I feel like it helped pull more water out for the flush and could be beneficial with adding air to the root system.

Just a thought.
