do not cut off parts of leaves, your yield will diminish a great deal if you chop alot of the large fan leaves off, plus their is no reason to make sure "to get some light to lower leaves". when flowering, i will take those large leaves and just gently bend them around a bud if they are shadowing it and i may do this twice a day then entire flowering cycle so i dont have to break them off. had a buddy who refused to listen and broke a bunch off a plant to allow light to buds and his yield was crap compared to what i would have brought in on the same plant. 85 is too high when you flower you will have problems, i know it says under 85 but that leads me to believe you are close to 85 when you should be around 75 only. the wrinkle is likely from cutting a leaf but ive seen that here and there for reasons beyond me and it isnt a problem, your plants overall look good no worries!
