yellow leaves have less cholorphy?

[dank smoker420]

do yellow leaves have less chlorophyl since chlorophyl is green? would the yellow leaves pick up less light or have less chlorophyl so it doesnt photosynthesis at the rate at which it would if all the leaves were green

 

[MasterCheif420]

I would think so. Not an expert but when leaves turn yellow it means they are useless to the plant, imo. I just cut them off

yeah thats what i think and do also. but people who have yellow leaves during flowering and say that its normal and what not. you think they lose yield? since the leaves arnt as good at photosynthesis

Yellowing of the leaves in late bloom is called apoptosis. It is the result of the plant translocating the green chlorophyll to nourish the buds in final ripening stage. It's completely natural and it's what you WANT to see. If your plants finish with their leaves all green, I hope you like the taste of chlorophyll.

And people with good translocation in late bloom GAIN yield.

He is right. i was talking about yellowing leaves in veg stage

Yellow leaves while the plant is growing generally indicate a nitrogen deficiency. The plant needs food!

Yellow leaves LATE in flower are normal. These leaves are dying, and they SHOULD be removed, because all they do is block light hitting viable parts of the plant that can use it.

Incidentally, the term "apoptosis" refers to self-programmed individual cell death. While individual cells in yellowing leaves probably do undergo apoptosis, use of that term generically to refer to plant leaf yellowing isn't technically correct.

Now, to answer the original question:

do yellow leaves have less chlorophyl since chlorophyl is green? would the yellow leaves pick up less light or have less chlorophyl so it doesnt photosynthesis at the rate at which it would if all the leaves were green

Yes, yellow leaves lack chlorophyll.

Entirely yellow leaves do not conduct photosynthesis, so any light hitting them is "wasted", or at least wasted, with respect to not contributing to growing your buds indoors!

Imagine trees in the fall, where the leaves turn all sorts of colors before they die and fall off the plant. That's basically what happens to the leaves on a cannabis plant at the end of its flowering cycle. Normally, flowering ends in the late fall, right before winter arrives, so the plant is going to soon die anyway. At that point, the plants main concern is making sure its offspring (ie seeds) survive, so it diverts most of its energy into the buds at the expense of other leaves.

Incidentally, its not entirely clear to me that cannabis plants actually move chlorophyll from dying leaves to viable ones, or even can do so. But regardless, totally yellow leaves typically fall off the plant within a relatively short period of time anyway.
