Looks like nutrient burn from the leaf tips, check pH, and lower nutrient feed amounts.
Also she looks a little windy swept, are the fans on her directly ?
Air should circulate, and gently make plants wave 👋 of there shaking / bending / turned up and leaf edging could be this issue.
Also light appears to close, the leaf edging is sharp and curling upwards. If using LED lower intensity, if HPS go for a higher placement.
Hope this helps bud 🤞💚
