copper tipped leaves

hello riu, im growing for my first time outdoors and i ran into my first deficency and i cant figure out what it is. so far its been transplanted into MG and i have veen using 16-16-16 for about a month but i dont think its nute

burn, but please tell me what you think and a remedy for it please and thank you


!!

Looks like the beginning of a K deficiency.
How often and how much are you feeding?
Last time you fed?

It looks like calcium to me, however it typically isn't seen outdoors.
What soil are you in, is it acidic?
What ph are you watering with?

I don't think it's a deficiency of anything.
I think your ph is off.

thank you every body, its in MG right now and i water every two to three days depending on the dryness of the soil, and each watering i use 16-16-16 all purpose, do you think i should scale back the dosage i use, or do you think i need to back off of watering each time with the 16-16-16 and should switch it up with water every other watering?
