why are the fan leaves yellowing out?!?!

recently noticed slowly day by day the larger fan leaves are starting to fade. nothing at all except her fan leaves pretty much but i wonder why my soil mix is meant to get her through her entire cycle. she is a re veg if that means anything
shes in ffof base+ super soil mix
always watered with a ph range of 5.7-6.8
either with plain water, silica, maxi crop seaweed extract.

Could use some magnesium so probably calcium too.

Been in that soil long? Just seems a little hungry to me

about a month, was on the verge being root bound in flower so i transplanted then she re vegged, of or so i believe i top dressed some compost and castings so ill be seeing what she does next i guess, any idea what it could be?

Hi John,
The revegging took a little extra time and nutrients from soil...depending on when and how you transplanted. It's hard to get a full run in soil without some nutrients added.

Hotrodharley said add mg, but I disagree. On the bottom right pix of the fan leaves...it looks a little like mg deficiency EXCEPT the fading is at the veins and not between them. Big difference.

Lower leaves turn yellow as Nutrients are drawn from them for new growth. Let them go completely yellow and fall off by themselves.

Generally looks OK...good job.

Nitrogen, I'd say... Try top dressing with some super soil

blood meal, fish meal, ewc....
