Sun scorch vs. fertilizer burn

Midwestener

I am new to gardening. I planted a weigela shrub last spring on the south side of a structure. It gets no shade until about 6:00 P.M. I fertilized it every two weeks with Miracle Grow liquid plant food at 1 tbsp. per 1 gallon of water, but I did not apply the entire gallon to the shrub. I did this for 8 weeks. Now this shrub is getting brown leaves down inside the plant and also getting burnt tips sporadically on the outer leaves. I stopped using the fertilizer about three weeks ago, and have been deep watering just about every day, but the leaves that are brown on the tips keep getting browner and browner until the entire leaf is dead. Some of the smaller twigs inside of the shrub have been defoliated.

We have also had sustained drought and 100+ temps here as in most parts of the country.

So, does anyone know if this is fertilizer burn or sun scorch, and will the shrub recover next spring from either one? Is there anything else I can do to help this plant?
