1st grow 2 sativas and 1 indica

Hey just wanted to know any good tips for my first grow. It is day three for the indica which is about 2 to 3 inches tall. Actually burned it from being to close to the UV light but its recovered. The two sativas are 4 to 5 inches tall and its day 5. On a 24 hour light cycle and they are doing fine. They are also bag seed.

Ok so ive cancelled this grow and threw out all incriminating evidence because of security purposes. They did grow and do what they were pose to but never got to flower them. I do have some vegetables and flowers growing and if you wanna know why its because to truly love growing cannabis you have to love botany and everything that comes with it. Ive been growing plants and flowers for years and find it therapeutical.
