?mid-late flowering fan leaves dying-not typical

Our plants are starting their last few weeks of flowering, and our tallest has started having problems in the last week.

The plants are in 5 gal containers, using foxfarm happy frog potting soil blend. We have been watering with a combination of botanicare products according to a feeding schedule, and the plan shifts around a room that has both a 600hps and 400mh that are raised far enough so that the plant is not being burned by the light. The room has good air circulation, and it has been pretty rainy outside, so no heat stress I can think of.

We do have a small heater in the room, but as I said, the plants rotate and it is never pointed towards them.


We flushed the plants right after we started seeing these signs, assuming it had been an over nutrient problem, however it is only in our biggest plant, and it seems to be spreading around its fan leaves, but not to the other plants.


I have scoured the pictures and previous posts on here, but can't seem to find anything we are doing wrong.
any suggestions or help would be much appreciated thank you!

The leaves feel dry to the touch
