Should I delay flowering?

Yes, you should delay flowering until growth resumes normally. In future, let you plants recover fully from being transplanted before giving any type of feeding. No matter how careful you are, transplanting can/will be a slightly traumatic experience for your plants, with root damage being the main culprit. It will take a safe 3-5 days for your plants to fully recover from transplanting and resume growing again. Feeding your plants so soon after transplanting will mean that as your plant has not had a chance to fully repair/recover her root system and any feeding of nutrients will overly tax your plants ability to cope with the nutrients, when all she really wants is some plain water to re-establish herself and her root system. This will be the reason for the burnt leaves, too much nutrients and not enough "recovery fluid" or as it is sometimes known, plain water. Just like people who have had an operation, they are put on a saline drip to boost their electrolytes and to combat dehydration and are not given a 5 course meal. It is the same with your plants, they need a while with plain water to rehydrate themselves from their operation (transplanting) and need time to heal before being given a healthy meal. The burning occurs because your plant can not supply itself with enough fluid due to root upset and the addition of nutrients actually dehydrates the plant through reverse osmosis, causing the leaves to dry out and burn.
