Mate you are going through exactly the same process as I did on my first grow. I did a few things wrong (not saying you have) and made some bad choices (won't specify but same as you basically) but got through it and grew some buds.
Second grow I got much better environment sorted, better light source and kinda found "my style" (TaNg's lol) and it's gone sooooo much better. As has already been said here just relax man
I literally sat in my bedroom with the tent for 10 weeks on my first one and nearly sent myself mental! I have learned to chill out a lot more (not completely!) and just watch them do what they do when conditions are good.
It will all sort itself out brother and before you know it you will be holding a big glass jar full of bud that YOU produced!
You're doing awesome mate and all the real good growers (not me) will always be there to help and guide you.
