Not sure if this is youer problem, but what the heck. The crispyleaf usually indicates, in my grow, that there is limited or no transpiration going on in the leaf. Usually the plants closest to the fans are afflicted worse.

Do you have fans or the A/C blowing directly on the afflicted middle to lower parts? If too warm, and too strong of a wind blowing on them...can affect the plants transpiration, causing necrosis. The plant can't replace the moisture loss caused by the heat/wind fast enough for hydration of the leaf tissues. (pale-green leaves, increasingly crispy over time)

Living in the desert, I fight this battle hard and often, and even with the best of care...I still get the crispyleaf, but the grow continues, lol.

If this doesn't seem likely in your case, please disregard the following, and keep in mind, it goes against some folks' conventional wisdom., lol:
What works in my enviornment (heat) is to:
Keep humidity down. Heat and dead spots (low wind) can cause mold.
Discontinue foliar feedings except to correct deficiencies. Tends to burn the plants. (every drop of water is like a little magnifying glass)
When foliar is necessary I raise the 400w lights till moisture is absorbed or evaporates.
Pull fans back a bit, aim the airflow so as to push the heat up, and raise the lamps a few extra inches.

This is basically how I get away with an outdoor flower room with (outdoor) temps in the 120's, and humidity at around 9%. No matter what I do, I can't keep the flower room temps below 90 during the day, but have been doing this sucessfully for years.
