yellowing leaves (no nutes) then falling off

i have recently noticed that on my plant on all of the kolas i have about 12/plant (i went with the LST method) all the leaves starting at the bottom started to yellow not wither tho and then just drop off. im not using any nutes at all as for this time im jus practicing for my large grow after i harvest. could this be serious or jus part of the life cycle

its part of the life cycle the lower leaves will die

but it almost looks like its morkin its way up my buds but it seems to only be my big
fan leaves but wouldnt that lower my ability to use the light in photosynthesis effectivly?

well hmmm did you say you were using "NO" nutes, don't think that may have a teensie bit to do with it?

The plant grows new smaller leaves on the buds and stops feeding the fan leaves. The fan leaves turn yellow and wither because the plant is no longer focusing on vegetative growth. The new leaves that grow on and around the bud sites are more efficient at transferring the light energy than fan leaves.

oh nice Untold thanks for the info +rep big help to make me understand a lil more

That's what we're all here for good luck on your grow!
