Other than a slight Nitrogen (N) toxicity and Calcium (Ca) abundance there's no signs of stress, those yellow blotched spots might be from water drops left on the leaflets while manually irrigating! If the blotching persists then it might be a due to the Calcium abundance but just to make sure upload another picture with the plant in whole, showing where the damage is and the coloration. Hope this helps! Good luck and happy growing :)

looks like your girls are screaming out for calmag. The rusting will have begun mid flower I expect?. if your using led lights and/or coco , tje loss in the magnesium is mainly these culprits on indoor grows. It 8s made worse during flushing as any goodness is washed away as you leech the soil/coco etc.. Always a good idea to have some calmag handy as you go into flowering as this is when the load is heavier for mg. I use it as a rule of thumb now as led is known for this issue..this coukd also be why they haven't fattened up more too.
