Several things:
Edge and tip scorch= fert burn
Soil= WAY too wet
Pale stripes between veins= Mg deficiency
Red petioles= Sulfur deficiency
That pot= I'll bet it has a built-in tray... TEAR THAT MOFO OFF!!! And drill some more holes in the sides of the pot if you like, you need better drainage.

All these things together= I'm looking at soggy soil that is probably out of pH range, making your plant exhibit both burn AND deficiency. You will have a bitch of a time flushing with that tray on the pot, but flush- test your runoff pH and adjust the flush water accordingly. Then on the final flush add a complete nute with micros, at 1/4-1/2 strength. You need those micros and a foliar feed wouldn't hurt either.
Also, did you slice up that peat pot before planting? Roots DO go throguh them but not as easily as advertised lol...
