Welcome to the community new friend. Plants are looking good for first grow. Lights are one of the most important pieces of equipment that you need. What kind of light are you now using? Plants will stretch some in flowering stage. My first grow with no experience no plant training, weak T5 light and plants stretched like crazy. But I became addicted and improved enough by forth grow, from putting into practice what this group of awesome growers told me to do and my yield went from 2-3 zips to around 9-10. My goal is a lb next grow per plant. Here’s a picture of my first grow super silver haze, and my 4th grow super skunk. Good luck
