Hi, well first time is the hardest time...and you can do some things better.( you always can, in every grow^^).................................... the Light is to far away from your girl . I always use very small lights(2x26 watts)very close to them, to let the plants grow in the first 21 dys. ..............................then i go with the bigger lights. But if you dont havesmall light, go a little closer until she stops stretching for the Light. and pay attention not to burn her. and you are sure to go with dwc in your first grow=? its very brave,......... its a complete new experience for you, you dont know growing, never looked how your lights work, and so on............... my recommondation would be: start with a soil grow, until you are used to grow, how your lights work how the hole system works..... BUT i dont want to discourage you. I know a few grower who started with dwc and mastered it very well.......i wish the best for you and i will follow up to look , how you are doing. Happy and successful growing
