Cytokinins is the flower hormone and balances the auxins. It looks like you may be a little auxin dominant. Plants need calcium to make cytokinins in the root hairs. Calcium sulfate (gypsum) has a reproductive energy but can get hot because of the sulfur so keep the EC of the mix 1,000 points over the EC of the water. Powdered milk is calcium gluconate and is very low EC and absorbs in about 20 minutes. 2 pounds per 100 gallons. Manganese has a strong reproductive energy and may help you tip the scales toward flower. Ammonia sulfate on the soil will cool off a soil warming up too fast. 100 pounds per acre applied to the soil. If ammonia sulfate is not an option maybe some fish or carbs to bump the soil microbes to help out. Cherries have a cobalt requirement for calcium bioavailability immune support. Always add white sugar to your foliar. Plants are carboholics! Just thinking out loud… Good luck!
