Help identifying if I have issues.

[Foster823]

These are my orange sherbet and zikktle autos. They are on day 66. Both or in Fox Farm OF/perlite 3 gal pots. I’m feeding them FF tiger bloom I/2 dose (1.5 tsp) every other watering. Run off ph 6.5. So my concern is how they are fading. Is this because of flowering or am I missing something. Any help is much appreciated

They're done soon.

Looks like there could be some powdery mildew. Few things you can do during now or even harvest time you can dip them into a peroxide bath mixed with water and then dry them out quick. Or just spray them with a product called Dr zymes while still alive.
