Hi guys.

All the large fan leaves have completely turned yellow and all the leaves have discoloured brown/yellow and are curling upwards like elf shoes.
Was feeding every two days. Have also flushed the soil out recently.

To me you’ve got two issues yes I see the nute burn as feeding every two days is way too much. But he plant has likely been watered too much making it very tall and lanky. So the top of the plant is too close to the light (which is why the leaves up there are very thin and small) and the bottom is too far away which is why the larger leaves are yellowing and dying off

Our friend @DudeGrowsWeed is right, this strongly looks like a nutrients burn/lockout. You should flush your soil for a couple of days with plain PHd water, and let it dry between each waterings. Also, are you sure your PHmeter is correctly calibrated? Your symptoms could also come from a PH related issue, I recommend you to calibrate your tools as frequently as possible (I calibrate them after each harvest). I'll be around, good luck with this giant plant!

Looks like nutrient burn overall to me. Burnt and curly leaf tips are a classic sign of nutrient burn. Yellowing leaves during flower is typically due to too much nitrogen.
