Hot temperature outdoor

They a bit small to be flowering, Are these an autoflowers??? If they are autos somethings to help prevent them from flowering early are do no transplant them and do not perform any high stress on them like topping or mainlineing. They also do not like really strong feeds, can give them 1/2 to 1/3rd the regular strength at times. As to much fertilizer will cause early flowering as well. They should be fine in 30c weather, just keep em watering and the roots chill and they will be ok. The bottom leaves look like some thrips have been at them, might wanna look int a spray before flowering fully begins. Good Luck!
