Yeah bro, whats your climate. If it’s cold keeps the roots warm. But man i fooked up this year too. Started in coco only… never again. Use potting soil mix of any kind and amend it with organic nutes. Your probably have tooo much light too at that stage. Back off the intensity. About 3000 lumens per sq foot. Im not a fan of blurple. So no idea how 3000 lumens translates. About watering i pull them from the tent, water until the run dry. So soak them good , wait till no more run off and put them back in.you can tell they get dry when the leave droop dowards. A couple days. I keep them around 75 degrees dont pay much attention to the humidity just check for they need water. I started week 1 on jan 6 and here is what they looks like so far, from seed. About 14” tall. Probably going to flower this week. After i transplant into larger pots. Currently 3 gallons. They take about 3-4 days to stabilize in my case.
I’d like to say this is the first time i buy seeds and plant them. Questionable… And I’m not impressed yet. The smells I nothing impressive and weak IMHO… hope it’s worth the time. My personal blend is much more aggressive growing and forgiving, definitely better smelling. Good luck buddy take care!
