Height ok?

Moving your light up will make them stretch a bit but I don't recommend it. They are growing beautifully. Remember they will at least double in size the week after you flip.

Height doesn't really matter much tbh.. As long as there's enough space for the buds to grow. Height is basically the plant stretching upwards to get closer to the sun, to absorb as much light as possible so it can use the energy from it to break down the nutrients in the soil and grow bigger. Since you're using an LED, you can always lower it as needed, if you want the plant to be closer to the light, depending on the heat the LED produces - IF you want it to gain height, then just raise the LED instead, and it'll start stretching more to get closer to it.
