Looks like a classic case of N deficiency. When you discontinue grow ferts (N specifically) so early in flowering, fan leaves yellow and die at a fast rate from the bottom up. You should be adding at least some N for the first 4+ weeks of flowering with most strains. Personally I keep adding N past week 8 although in very small amounts.

I'd recommend giving them a 50/50 dose of grow/bloom next feeding and then back to bloom only until harvest. It will keep your fan leaves alive and happy and making energy for your buds.

Red stems on dying fans are another indicator of N def.

I'm pretty sure FF adds dolomite lime to OF, so although mg might be part of the problem (like buddy said) it might not be a deficiency. Its no surprise most people notice mg problems around week 4 of flower, because they're usually stopping N entirely and loading P/K and P/K toxicity will lock out mg and show many of the same symptoms as mg def.

Getting a soil test kit might be your best bet here. They are cheap and you will immediately know if mg is a problem.
