Brown/Yellow leaves in flower, nute burn, high temps or something else?

Hi all,
I have 2 ladies in 10 gallon pots of Fox Farms Ocean Forest mixed with Happy Frog.

I have been feeding FF nutes with some Ful-Power and recently Cal-Mag in pH balanced water.

They are in a 5x5x7 tent and under 1500W of LED lights.

I don't have any dedicated ventilation, but vents are open on the tent on the top and bottom, and temps have been between 92F (high when some vents were closed) and around 84F now peak.

I will post some pics in progression, please give me some suggestions. The browning/yellowing seems to be more on the top leaves, and started on the larger plant first. It seems too early for it to be due to nitrogen use during flowering.
Here they are in chronological order, starting about 10 days ago:
