It will have an impact but it wont be life threatning to your plant . Take it as a learning lesson and try avoid the same mistakes for your next grow :) This is how we learn . I also might suggest that you slow down on that nutrients . Thats a very strong mix for a plant that small . I would reduce the strength by half maybe even 1/4 and work your way up as the plant grows . You typically dont wanna start going hard on the nutrients early like this so that you dont burn the roots leading to what we call nutrient burns or toxicity of nitrogen or other compounds . Other then that your well on your way to getting yourself some nice medicine ! I hope this information helps shine a little light on whats going on here . - Happy Growing!
