Fan Leaves of Cloned Plants Change #

[recent guest]

I have noticed that the fan leaves of plants grown out from clones have morphologically different leaves than the original seed mother. They are of a slightly different shape and often have a reduced number of blades. Has anyone else noticed this?

Has anything changed? Could you be inducing phenotypic variation to be expressed?

Leaves show irregular growth patterns when taking from a flowering plant. Single bladed leaves, twisted "rams horns" etc.

I defoliate, prune and train the plants pretty extensively and have noticed that clones of some strains respond to the defoliation by growing lots of smaller fans instead of fewer, larger type leaves found in plants from seed.

A cutting will most often look different than a plant from seed of the same strain, even the plant from which the cutting was taken. I believe this is because the cuttings are starting life from a much later point. They are already mature in a sense. They have different priorities than a seedling.

A seedling with the biggest leaves can catch the most light. They have to outgrow neighbors for good sunlight and a shot at reproduction. They have to grow fast to reduce the chances of getting trampled, eaten, blown away, overshadowed etc. Survival instinct type stuff. Once the plants are established and have grown past their most vulnerable stage, the reproductive instinct takes center stage. Different biological mechanisms, different environments (seasons), different nutritional needs.

A cutting has already made it through all that. It grows like a mature plant even though it may be small because it is just a piece of a mature plant.

At least thats what I think. Could be a calmag deficiency as well ; )

If you veg em long enough they come round to normal but alot of people will flower before hat point!

I agree with that ^

let me see if i can drum up some example pics of what im talking about:


ok, here is the mother plant. Notice the HUGE fan leaves. It's a Diesel -

And the plant in the back right corner, the largest and bushiest, is a clone of the plant pictured above. The above plant has 9 bladed, long leaves, but this clone only has 5 bladed leaves maximum even though it has been growing for ~ two months now.

Yes. And, all clones tend to look alike. It isn't until mid-flower that clones really start to differentiate where you can ID the different strains.

What Tonygreen said is spot on.

once the plants are vegged long enough for the fan leaves to go from opposing to alternating (which is when many take cuttings and start 12/12) the fan leaves begin to change from high # of fingers to less...

I've noticed that they don't revert to large fan leaves but retain the size of leaves they had at cutting...haven't ever really let them though.

mmm.... the only thing i could think of is the cold night temps,mine have not grown so big because of it,i would say it to be quite common ! atb.ww

Im going to have to grow out a clone for several months before flowering, so I guess I'll find out what happens.
