Leaf tips turning purple

[Airbone]

Anyone know why this clone is turning purple at the ends of the leaves? The plant I took it off of in the outdoor set up does not look like that.

Insufficient light and nute imbalance.

Under a 24 hr 1500 watt led grow light. No nutrient yet just transplanted that to soul today. They been under the same tap water and only that plant did it. Also the first one to root.

Cute little setup...
Beginner grower as well, I to have tried growing in a clear pot/container.
Had a great deal of algae buildup and the sun/bright lights turned the roots green.
Also, have dealt with purplish leaves. A good flush and lighter serving of nutrients might help.
Don't forget that a lot of newer/organic soils have a good helping of nutrients to begin with.
Also, check you water PH.
