Be aware that that dosage is the one you should take as maximum, not recomended. Its put there to treat deficiencies. So to use it at every watering, as supplement, dilute it more.
Btw, your plants still look good for the fact that you dose your nutes by the tsp. Using an EC meter or TDS meter would take a lot of the guesswork away. But I guess you could also watch plants closely and try to corect it this way, it seems to work for you. Just feed less N next grow, switch to flower nutes faster, and I bet you'll have faster and better yeld.
