Most all nutrient deficiency show at the bottom leaves first, with the exception of calcium, which is a very common deficiency while growing in coco and I dont see any listed un your nutes. There might be some nutrients overdose too, lower your feedings between 1.4EC to 1.8 EC, there's no need for more than that.

Hey man i don t think it's P deficiency, actually you most nutes have too much P anyway, looks like sulfur deficiency, flowers usually need it around the time they starts their flower stretch and start getting fat flowers. Get some mag sulfur next grow you'll see 😎 🚀 good luck looks great by now already !

Your temps are around 82, which is at the higher end of things. In my opinion, I'd say it's light burn. It happens to my buddies plants a lot. Try lifting your lights a few inches and see if it helps? Light burn affects the growth closest to the lights. It also looks like it could be ph fluctuation, but I doubt it.
