I do soil. I'm also in my first grow, but I have gained a ton of knowledge by being here. I might not be able to answer, but what you got going on.
Answer t i one of your question about j high dose of N.
You do need higher n for veg stage. Examples 12-6-6or 8-8-8. It dose not have to be a high dose. I prefer a little higher N for veg,but not a requirement. . This dose not create a female plant. Least I have never read or heard of that anywhere. I could be wrong. Growing a female is either an auto fem, clone, or pure genetics. Simply you increase your chance of female, by not creating a lot of stress, happy growing environment, and proper nutrients. Less stress better chance plus less problems, I'm in for this grow and here to help as much as I can. Just ask questions and keep up on the journal, and help will come. Great. Job. P.S. get away from mg soil or ferts.
