Yellowing leaves

As u see, the top and sides of your big plant are healthy and so on. And there's not an off looking leaf tats getting light. But the bottom with it getting no or not as much ppfd with what I said about the plant needing fluids (very lightly) this is the by product. Only now I can bring a pheno without this until I get to the crop steering process in fattening then I get lots of this. But to avoid it now at this stage everything needs dialing in. And rotating your plant also will help massively with this. As the sun moves as u know. So all sides are hitting it. So with static lights you need to imitate the sun amap. So moving your plant so it sits differently every 6hrs or even turn it 180 every day

Yeah, nothing really to be worried about bud. I use to get a lot of tat. Took me a long time to be able to fully dial my grows in tat curved this issue. Yet I still get them from light mistakes from the plant wanting feed. If u ever water ur plant and water runs out the bottom from just a few 100ml (and another day you could give 1L and you'd get none of tat) well when it does happen and even though ur plant isn't wanting but when the plant gets to tat. It eats the leafs closest to the root zone as they're the ones 2 1st feed your plants needs. Also, lack of light getting to those leafs pushes them to tat point. Crop steering folks get a lot of this. When they push the plant to the point of what I said above on purpose (de water pouring out bottom with lil input) it forces the plant in fattening to dig deep into her own resources and pushes bud expansion. They have a journal on it here.
