I always maximise my light.@Bill284
I will raise the lights in my closet.
Its 400-600 for veg right? 1000 for flower?
So the question is..... Will a plant getting 450 get just as much growth from a light as 600 for veg?
But if it's too much too soon it causes issues that impede rapid growth.
So adverse reactions indicate a too rapid increase in light intensity.
Either too close or too strong.
It's good to know the intensity of your light, but the plant will be the indicator in the end.
Take note of strength, distance and plant age size and reactions.
Helps going forward to have notes.
Back it off for a bit see the difference and her recovery then try again.
Stay safe
