Hey bud. In my opinion I would not stress unless you after a Cannabis Cup bud. If you have the correct grow medium, correct light and don't feed it all the kak marketing companies are throwing at you give it a few more weeks before you panic. I'm a newbie myself to indoor (3rd grow) but the KISS method works for me. Keep It Simple Stupid. No offense intended. Good soil, water and patience is my method. And because I can't afford the extra feed. Good luck, holding thumbs. Sent from my DRA-LX5 using Tapatalk
