so here is an overview.
First grow
I have 8 ladies in A 240x120x200cm room. 2x600 Watts hps In soil.
I don’t know if what’s happening is normal
During flower but my leaves are yellowing. My ppm is around 1100 so it’s a bit high. Don’t think they are hungry. Or are they.
Ph of soil is 6.3
Can I also have a prediction on yield.
I use bio Bizz nutes
Any suggestions.

You’re at the right stage for CalMg def. Are you sure your meter is reading correctly? What’s the EC? My first thought was k deficiency.

Yield? Between 0.65 grams per watt of actual output and bout a pound.
 
Nute burn. Some strains can tak

e anything you throw at them. Others you need to take care with. It's all fun and games
 
Try one tablespoon of Epsom salt per gallon of water on your next feeding. Maybe cut the nutes by a quarter. Your yeild will be 1 pound btw.
 
Start at the bottom and working up?

P tox - too much P too early... very common in new growers.. No booster use and less N drop for the first 2 weeks of bloom.
Simply feed veg nutes for the first 2 weeks of bloom and up the bloom nutes over the next 10-14 days to directed use.

Bio Bizz seems to have this problem, as I've seen it for years here....Odd too. Their #'s aren't exactly bad..

Start in the middle and spread out? Mag def. - like Nutty say's... This could also lead to other issues from it also. Including the P thing..

So then. Did it start at the bottom or in the middle?
 
I can’t comment on the yellow leaves but I can tell you the yield will be somewhere around a pound.
 
Make sure she has a little Nitrogen in those bloom nutes (if not add some) and as others have said make sure shes getting Cal Mag. Prob one of those two issues.

Yield can't be predicated as it depends on genetics and many other environmental factors.
