Leaf Damage, Do you know the issue?

The first photo is showing the beginnings of a phosphorus deficiency.... second photo shows a calcium deficiency (and the two often show up together). These ladies are now at the age where they need to have more than fish tank water... get them on a good grow nute as well as calmag. Looking through your diary and your notes, if you've got an insect problem (which is sounds like you do), you need to tackle it before it becomes a really bad infestation. The neem oil MIGHT help but in my experience is fairly ineffective especially since it doesn't get at the eggs and larvae of whatever insect you're battling... and, as you rightly point out, you shouldn't use it when the plant is in flower... If you've got white spots on your leaves, it's likely you've got either thrips, aphids, spider mites or whiteflies and you can catch SOME of the adults on those sticky papers - but you won't catch all of them and you won't be addressing the eggs or larvae. I would suggest grabbing some Dr. Zymes Eliminator or some Spinosad and using as directed. Both are organic, both will kill all stages of an insect's life cycle and both can be used at any stage of the plant's development right up to harvest if need be without affecting the buds or the taste. Addressing the problem NOW while the plant is still young and easy to work with will be far preferable to having to deal with it later when you've got a jungle in your tent - you have to spray the tops and bottoms of ALL leaves... you see my point here... The only flying insect this stuff won't work on is fungus gnats... those actually live in the soil and they don't suck on the leaves at all so that's not what you're dealing with anyway... Good luck - get some NPK nutes into her along with some calmag and DO deal with those insects now before the job gets exponentially harder!
