I have noticed that bottom leaves are turning yellow (later even brown) and then falling off. I'm just 2weeks into flowering. Is this normal? If not, what should I do? For more info about my growth please check my signature.
in my experience(3 grows) it's normal. They have served their purpose of supporting the growth of that node(branch)until it was fuly formed no longer get the light they one did so the pant reasorbs the nutes from the leaf to make new leaves/buds in the full light.
