@Findthelorax Until those roots have reached the nutrient solution and the plant has started actually growing
you don't need the solution to be so "hot" ie full of feed
Also PH should ideally be lower than 6 to allow all macro nutrients to be uptaken
5.7-5.9 is good
Watch the temps of the nutrient solution as it will effect the health of the plant
and oxygen levels
Keep light away from the roots
Good luck
