Usually, brownish/red hue on the tips is a sunburn. If its stretching out and the brown tips are on older leaves, you can just cut those lower leaves off. Roots grow from under the oldest leaves on the stem base. The lower leaves can just be peeled off. I currently have over 100 Aloe Veras, and just pulled off 57 pups off of 5 of them. This is just information based on my experience.
