First time | ILGM Agent orange

Everything seems to be bumping along smoothly, besides it being a dense and hard to manage bush. I was using regular tap water for my humidifier and it was causing mineral dust to built up on the filter big time, replaced it with a new ipower 4" filter and I'm using distilled water for the humidifier now. It also seems like my c02 is running low or is done, so I put in an order for the refill packs. Temps are ranging from 78-84 F and RH is between 55-70% all keeping within a VPD chart(some what). Started LST around day 27, it's pretty awkward to do as it's really short and stumpy, but I took my time and tried to do it gradually. I fed her on day 24, day 26 and day 29 about 1/3 a gallon of calmag/bloom big. I see zero reason to add the other nutes as I have no clue how much of the FFOF soil's existing nutes it's used. So to wrap up this week I do have some questions I'd love to see some feed back in the comments -Are larger leaves touching the soil an issue? -When do I trim fan leaves? -When should I start adding the harder nutes? -Is the LST being done efficently/correctly? -How many more weeks in veg would you give it? (leaning towards 2) As always thanks for taking a look and feel free to give me as much feed back as possible, this is my first grow, no matter how good it looks 😏 EDIT: the other cups are Chocolate Carolina Reapers/ Genghis Khan Brains, I might sneak a picture in here and there if you guys like those kinda things.
