Looks like slight cal mag deficiency. A little over fed and let it dry out a little. The fan leaves sometimes start yellowing as you get nearer to the end. Move the light back a little more from plant. Serrated edges starting to point up. One of the signs of heat stress. I am not an expert just trying to help.

Disregard the breeder seed estimate about harvest time ... It is always longer than advertised.

As far as leaf issue : needs more PK ( lower nitro higher PK ) like in your Bloom only nute.

Cut off that bad leaf so the plant won't try to repair it. Leaves will fade naturally as flowering continues. Buds look like they are adding weight.

look like Potassium deficiency, question is whats causing it as can be down to too much of something else causing a lockout of K or just not enough K being fed
