MarcXLanswered grow question 5 years ago I see some problems here.
First the white spots on leaves are most likely thrips. Common even indoor. During flower there is nearly no chance to get them off the leaves as you shoudn´t spray anything by now to the buds.
Also they seem overdosed with nutrition, dark green leaves everywhere and burned tips.
In this stadium of 9 weeks of flowering the ladies should be nearly ready for harvest.
If these were my plants i would defoliate most of the (infected) leaves and start flushing properly to get those nutes out. Harvest soon, maybe 5 to 7 days after flushing. They look ready for harvest in one week.
What ever may have eaten those leaves, no idea.
