Leaf tips turning brown and curling down

[Nabber]

Hi
I got a clone 1 week ago and have no idea what week of growth it’s in. Trying to determine what is causing the leaf tips to curl down and slowly turn brown. Wondering if it needs nutrients now. Transplanted in Pro mix Organic moisture control soil.

I am using a full spectrum 400W LED grow light and not certain what height I should be above the plant. Maybe it’s getting too much light. I’m new to growing so any help is welcomed.
Thanks

A clone is the same age as the parent plant.

Light should be 30 inches above the canopy for the entire grow k. Measure it with a tape!
What are you going to feed her?
Once you move the light the washed out light green will go away and she will be looking for something to eat.
Get after her with some fertilizer. Look for around 300ppm Nitrogen for a young plant like this.

I’m going to try feeding tomato fertilizer this time. Trying to keep the grow cheap as possible. I’ve moved my light away from the plant so we’ll see what happens.
