As a rule of thumb, your first grow should be in soil. No nutes.. No LST, no supercrop, no topping. Just seed into wet nap, transfer into 1 gl pot, veg 30 days or until your plant is a foot tall and has 4 set of branches, then flower until trichs are amber. No transfers of any sort. Your job is to check ph and practice your watering technique while making detail notes on any changes. See if you have what it takes to grow and flower a simple pot plant. See if you have the patience and time to do daily upkeeping.
You can do a full mature cycle in under 100 days from seed. You wont get much but it'll be enough to feel proud and accomplished.
Just saying it sucks not know the basics when trying to do something advanced.. Learning the hard way has no curve when it comes to grows. Sometimes you have less then 48 to diagnose and fix an issue before you're screwed. You want to be ready..
Good luck.
