White widow auto leafs problems?

Hi, im growing outdoor an automatic White widow by royal Queen seeds
I've found this spot on One leaf and i'm worried
The plant Is probably 14 days from harvest
She's growing in a pre-fertilized medium soil and i've occasionally been giving her an npk booster by Bayer 6-5-9
What could be the problem?

It looks like insect damage to me. Check several times a day and at dusk to see what is sucking the sweet sweet juices out of the leaves. It's a small spot and nothing to really freak out about, yet. If you do find insects there are several things you can try. Insecticidal soap works well, but you need to wipe it all off after applying it, because it will burn the leaves. Neem oil is also effective at treating for bugs.
