I'm still relatively new to growing but to me it looks like nute burn. Try backing off on the nutes and check the PH of the water. Good luck!

It is def nute burn... I wouldn't use 1tbsp with the plant being that small. I accidentlly did the same thing using the same product and the same shit happened...you really don't need to use the nutes till it has like at least 2 or 3 well developed nodes...
