why do i constantly see people leave so much yellow leaves left on the plants near the finish, i have always thought the reason for letting the plants grow towards the end, is to fully compleate the last part of the grow cycle, and with yellow leaves shading the remainder buds this would slow and impede the speed of this last stage of the grow cycle to fully finish, atleased slow it a bit, plant parts they need light to finish, the more light on the buds the more growth the more growth the faster it takes to finish
now i know these yellow leaves help protect buds and the resin glands from rubbing, but with carful handling, thats another story
only other thing i can think is this is just a flushing step and these crops i see everware, have all ready fully compleated there grow cycle and are simply waiting for nutes to leave
am i the only grower on the planet that cuts off yellow leaves
Even though a leaf is yellow the vacuoles are not depleted. In my opinion, the yellow leaves are left on to allow the plants to draw on the reserves in those leaves to prevent yellowing of the buds. Another key reason is that the plants have to close wounds up when you pluck leaves and still create stress hormones related to being “fed” on. Creating weakness can allow pathogens to take hold. Plants are basically 85 year olds at this point. Anything could take them out. Truly dead leaves shrivel and die. The plant simply blocks the sap flow through the leaf when it has finished with it. For many people it is just a sign that the plant is ready for harvest and looks pretty.
thanks man, you explaind that great, learned some thing that i have never new about, i will leave those yellow leaves next time, and the time to remove them, is when they are dead, seald up, and drained of there nutes.
