Well, you don't have a diary so the information we have is limited to those things you feel are important... All I can say is that each plant will react differently to the same care/nutes/conditions and you have to treat each plant individually. What is it you're growing? Auto? Photo? What's your substrate? Indoor? Outdoor? How are you watering - manually? Drip? Is this hydroponic? There's just too much information missing here to give you reliable advice... sorry mate!
Good luck
