Nutrient problems

Im having a problem with my plants while they are in the flowering stage. They seem to be showing signs of over fertilizing and nutrient defficiency. Im using fox farm organic fertilizers. Comes in two different bottles one says use 2-3 teaspoons for recirculating systems so i use 1 and 1/2 teaspoons in half a gallon. The other says use 3-4 tablespoons every watering so i use 2 tablespoons per half gallon. If anyone has had experience with the fox farm products any help would be appreciated. Also if you are getting good flowering results with a particular fertilizer let me know how you do it.

and im also ph adjusting my whole thing to 6.8 and im growing in fox farm soil.
