Looks like light burn to me,how close are the lights?

What Potted said. What did you do different❓also double check your pH , before and after ☮️

[Cindy Nightshade]

It’s light burn. Your light needs to be 18 to 24 inches above the top of your plant when in veg and when in flower 12 to 18 inches above.

I haven't done anything besides putting in that light for flowering time I went from 120 to 300 should I have kept the 120 on it and i keep tabs on my pH but I don't I check pH after watering I will start also what should I do if moving the lights higher isint an option

[Cindy Nightshade]

Keep the 120
