Hey guys, first time grower. Im currently growing a white widow auto indoor tent setup about 8 weeks in. Plant is sitting at about 1.3m tall. Ive noticed some of the tips of my leaves are discolored and one section of leaves in the middle of the plant has turned yellow. I have down a ph test and is all good.
Nothing to worry about, flower transition usually neglects certain leaves and sucks the nutrients out of them to feed the buds, eventually those leaves (fan leaves) turn yellow and die while the buds thrive.
