Dresden Green Diamond - First Grow!

So soon I am going to have to start making some decisions I think on how to care for this. The nutrients in the soil FoxFarms Happy Frog will likely run out in a week maybe? Again this is exactly 3 weeks from planting. So it should probably be week 3, I don’t know how to count. The site wasn’t letting me start with week 1 had to do germination and couldn’t save germ without a picture. I will try to see if I can fix this and shift them all 1 week forward. Again I am a rookie here and will do some reading up on all this when I have time but here are the things I don’t know that am starting to think about. #1. When to start feeding nutrients. I got a General Organics Growbox probably 6 months ago have kept it in my closet in room temperature. When do I start using it? Is it even still good? #2. Transplantation. This plant is growing so quick, I know this pot is too small. So I need to figure out how and when to transplant it and into what size container. This is a small tent 2x2x4. So I can only raise the light so high. And I don’t want to kill it during transplantation. #3. Training, when to start low stress training and exactly how to go about that. Need a plan for this. #4. Topping. When to top it, should I top it. Should I use a different strategy. Need a plan. #5. Humidity. I think I have a solution for this. I know what the humidity needs to be. I bought a humidifier but I did not buy a humidity controller may need one of those or just pay attention to it. #6. What am I missing? I feel like I’m forgetting something. Overall I think it’s going pretty well so far. Plant is growing fast and healthy though I suspect up until now is the easy part. Dresden Green Diamond seems to be a resilient plant, since I haven’t killed it yet. Thanks for following and for all your help I’m sure I’ll get from you peoples. Appreciate you. Merry Christmas, Happy Holidays, until next Monday. Ciao.
