Why Are My Leaves Growing Three Fingers? Let Me Tell You Why

[Seamaiden]

I think that needs to be more widely clarified, I'm reading it all over the place. I only relatively recently heard of Triangle Kush, but have known of The White for quite some time.

 

[Bulldog11]

Triangle and the white are one in the same. Grown both out but not at the same time, if not different than very close to the same genetics.

 

[WalterWhiteFire]

Triangle aka the white is different than triangle kush. Just confusing.

 

[Rootbound]

I have several difere strains that throw three fingers that arent OGs and are not revegging. Its in the genetics on mine.

 

[johnnyblazed]

my Chemdog D and Chemdog 91 have the 3 fingered leafs got to be genetics

 

[Seamaiden]

Mine have never had 3-fingered leaves, and I grow out a *lot* of Chem genetics every year. If you think it's only genetics, I think you've gotta grow out more differenter genetics. And in different conditions, too. If you can do outdoor as well as indoor, prepare to have your mind blown when you see the differences.

@Bulldog11 @WalterWhiteFire -- now I am even more confused. :o

Stress can make a plant throw out less blades.
Maybe the plant was too close to the light. Too small of a container. Photo period can cause those problems but is not the only cause. So if you do not have light leaks or messed up timer.
Check other ways the plants are stressed.

When you see the plants throwing out one to three blades vs 7 to 9 when she is happy and healthy. Og kush that is stressed out may start with 1 to 3 blades and then will develop to 5 to 7 blades

I notice once I get plants under brighter light (1000 watts) then they throw out the 7 and 9 blades. Some strains will not do this until they have grown 4 to 6 nodes tall.

Regarding the white: Both are correct.
Read the words carefully... NO kush after triangle.

 

[rubthe nub]

I use to run a seed strain for many years that grew only 3 leaflets until very late in veg, way passed the alternating node stage of growth. When they were young they didn't even really look like MJ plants, more like some kind of mutant strawberry type of thing. It would grow like that outdoors or indoors so I'm chiming in on the genetics side of things as well.

IME, the 3 leaflets or singles from a reveg often have little serration to leaf edges, I've even seen no serration leaves.

 

[Seamaiden]

Forgot to add that bit about the serration!

When I first began growing, I'd asked a question about spectrum and how it might affect growth. I was told I was overthinking things, plants just need NPK and light and that's it. Obviously, now I know differently, but when it comes to the light aspects for cannabis there is still a lot for me to learn.
This mention of other stressors and the change in light makes me wonder about Capulator's thread on nutrient uptake in relation to light spectrum and whether or not there is a relation to what's being discussed here.

@leadsled -- I've only ever observed this 'behavior' when photoperiod has been screwed up. Are there other stressors besides what you mentioned that may cause this? I've done rootbound, too close to the light (but not the sun), and screwed up timers, and so far only the timers have caused this to occur.

In addition to fatter wider leaves with more blades. Some strains will also throw double serrations on the leaves when healthy. Vs when less than healthy they do not develop the double serrations.

So when the photoperiod did not jack em up enough for me. I tried breaking stems, cutting roots, Irrigate with super cold water, Use of pesticides/fungicides, pests and diseases, excessive heat/cold.
This is based on observations from testing clones trying to induce hermie traits. Some strains can take the problems in photoperiod much better than others.
Have also noticed spiraled leaves with webbing from changing the lightperiod.
Thanks for sharing it helps to hear what others experienced.

 

[Seamaiden]

Thank you for sharing your experiences! Everyone. :)

The plants that are genetically prone to three leafs will show this trait all the way through flower IME. 99% of the plant will look normal, but you will find a shoot or two with 3 leafs. Honestly, I look for this and when I see it, I know it's going to be a good plant.

 

[shemshemet]

I have a plant I revegged 10+weeks ago and it's still throwing blades. It's a Hindu Kush and it puts out mostly trefoils when it's healthy. Anyone ever seen a plant that won't completely reveg?

The Triangle kush and Legend i run also put out trefoils consistently when they are perfectly healthy.

I took some clones a little later into flowering than I should have. They all took fine, but now vegging they are throwing pistils and trichomes. Trichomes all over the stem and leaves. Odd thing....I feel it may have something to do with plant growth hormones...maybe ethylene? I'll let you know if they ever stop this behavior.

Will they start out, like from seed, with triple-lobed leaves?

 

[Bulldog11]

IME, yes. They normally start out with the majority of the plant with three leafs. Then it works its way out of it by the 6th or so node. From there they will randomly throw out three leafs on smaller branches, usually sucker branches.

 

[rubthe nub]

The strain I grew would go even longer than that. Never even counted nodes but my guess would be 15-20.
Close to thigh high, but side branches or small branches would retain the 3 leaflet trait.

 

[MidwestToker]

I can vouch for the stressed out part. Had a SLH I messed up toping and it threw all sorts of messed up leaves and strange growth.

 

[juniper]

Bodhi's Pinesoul OG consistently grows trilobate leaves:


Some folks my friend works with said that trilobate leaves are a hallmark of real OG Kush genetics, and that without them, plants rarely display the desired"OG Kush" qualities (very little trimming, fierce lemon-pine smell, chunky triangular buds). Seems a bit reductionist, but I've never grown any of the standard OG cuts (Tahoe, SFV, Hell's, etc.) so I can't speak to that.

I thought the White and Triangle were separate strains, but one was an S1 of the other. They're both from FL. @Bulldog11 you said your cuts were very similar if not one in the same? @WalterWhiteFire Are your Triangle Kush and "The White" cuts somewhat similar? Or just totally different plants altogether?

[Seamaiden]

Nice job on that, @texasjack ! I've never been able to get a girl to go back once she's been harvested, so I''ve always just taken cuts.

I kinda like that linoleum, there, too. :o
