Starting to see brown around some of my edges and was wondering is it light burn. I know it’s not from nutrients or bugs. A little help please. Been using Mars hydro 200w light 18 inches from plant and added a small cfl purple 30w light to supplement.

Looks like the plants I started flushing a week ago. Classic hungry plant look.
But since it can't be nutes or bugs, and the light isn't too close, it must be improper watering.

Okay thank you this is only my 3rd personal grow never had this problem. Maybe this plant needs more water then plants in the past at this age.
