Yellow Leaf Problem

[LilChris]

Hi All,
Hope things are good. I was hoping to benefit again from the amazing experience on here. My plants are in week 4 of flower. I'm growing indoors with Coco, feeding them Canna A&B and FoxFarm's Beastie Bloom. The last few days some of the leaves have turned yellow (Pics Below) the rest of the plant looks okay from what I can tell.
Anyone got any ideas for best place to start in stopping the leaves going yellow and how much of a problem do i think it is?
Thanks in advance.
Chris

I wouldn’t sweat it. Later in flowering the lower fan leaves start to die off as the plant uses the stored nutrients in them. Might hit them with some calmag but otherwise they look fine. Looks like you are well on your way to a nice harvest. Kudos.

Thanks mate, didn't think there was too much to worry about but better to check and be safe than not check and be sorry. Peace & Love

Probably just normal for where your at in flower but I'd look around and make sure that isn't root aphids causing it.

All looks sweet, thanks though.
