Can anyone further advise me

Leaves will naturally degrade in late flower

Not sure if your nutes where adjusted to bloom phase, but looks like to much N,and could use a PK booster

Yes I adjusted them to as the canna chart states, I did add pk on the said week should I use again?

At this point, I would recommend not deviating from the product's feeding schedule. A lot of really smart people with PHDs have spent thousands of hours putting together that feeding schedule - it's never wise to second guess them unless you are an advanced grower.

Gather your data and photos - and we'll pull in more people to help if necessary.

OK quick update then, theve been flushed feeding at 5.8 to 6ph, temps or in check still seems like the yellows progressing, iv jst mixed new food and added some cal mag, I think personally now looking back I used to feel calmag every second barrel of mixed food, I also have always used moonshine... And not seem to get no where near as good results without, I could really do with working out what went wrong since I have 10 plants coming into flower tent once free to flower dnt want the same issues again really but I'm totally lost
