Yellowing leaves help please

Im flowering now but leaves seem to be getting yellow... have been giving cal mag plus also little of bloom nutes also i know theyre going to get some yellowing of leaves but not sure if its normal cause i dont want to give to many nutes... im not sure if i leave it alone it will be bad for plant. Any help would be awesome

Thanks riu

usually the bottoms will yellow and thats normal but if its towards the top you have an issue with nirto usually not enough if you could post pics i could get a better idea of whats what

I posted that thread twice on accident theres one right before it with pics.. thanks
