My plants reacted similar to this when I gave a good hard spray of neem oil. but it was on the upper leaves as well.

What time are you spraying, You should be doing whehn the light is off and when the plants have enough time to dry before the light comes on.

Every 2 days is a little extream in my opinion. DO you have a bug problem? Or just being a good lad and preventing a possible future bug problem.

hopfully your preventing a bug problem, IF so only once a week is neeeded. And only use it up untill 3 weeks of floweirng or untill decent flowers form. You don't want that oil to be stuck on yer buds when your going to pick them. You'll end up smoking shitty tasting weed.

this is how I have learned to use neem oil. im not saying its forsure the cause. but if you using neem oil every 2 days thats a bit over kill. I was told every three days is plenty and only if an agressive bug attack was present. I also heat my neem oil spray bottle in warm water for 5 mins before use to help mix the oil and the water. naturally Oil and water seperate.
If you have been using it neem oil weekly since it was a young plant till 3 weeks of flower it will have enough neem oil protection to really prevent bugs and their attacks.

You want to try and get your Ph runoff up a little. Try a watering with Ph 7 water. to try and get your runoff between 6.5 and 6.8.

Just one more thing your grow room looks kinda dirty... clean er up a little... hahahah:jointsmile:

Just my 2 cents.....
