I would not be adding much nutes at this point. If your soil is good then Ph correct water and light is all she should really need at week2 in soil. I tend to over feed and water in soil. If your feed schedule is correct I would say your over feeding a bit. Big bloom runs at max 6tsp per gallon of water at this stage, your running 36tsp per gallon (6tsp=5ml).
That said you can see my over feeding results in my dairies with ilgm stock. So far I can only burn the tips no matter how much I over try.
She looks about ready for your main lining.
