Hello, I popped 2 seeds and they sprouted coming up on 3 weeks. In the past it always seemed like they grew faster. This will be our 6th grow, still beginners in my eyes. We have a 2×4 tent with Mars hydro sp-3000, temp average is around 75 degrees, humidity is around 60%. Light cycle 18-6, soil is Promix HP. Was just 6.0ph water (today we added small amount of nuites as the leafs started to turn yellow). They are still in solo cups. Strain is LA Affie and Shishkaberry. My question is am I being impatient or is there something wrong? Any advice is much appreciated, thank you!
