Flush flush flush. Damage is done and leaves won't recover. But can stop it from spreading further. Use proper ph water till desired ph is in run off. Replacing any nutrition along the way. Always have a 20 percent run off and test ph of end part of run off. The run off washes salts out of soil which will spike your ph down if they build up. Chemicals used to grow leave salts behind. So have to keep pushing the old out when you add new. Good luck and happy growing

Unfortunately, you have a sativa dominant strain so your flower time should extend for 10+ weeks. Harvesting now would be a shame. In your position, I would start by examining every single flower for sickness. Remove any that you're unsure about. Cut off fan leaves where the foliage is dense to increase airflow. Get a couple fans rolling to circulate as much air as possible. An inline fan would be a great addition if you don't have one.
