The clueless first grow

25/01 The last couple of day's have seen a lot of new branches starting to form while the main stem has tripled in thickness. Pretty sure this growing out rather than up is my girl's way of prepping for flowering, I fully expect to see signs of pre flowers at some point this week. Probably a bit late but started adding some power roots to her feed, hopefully I'm not too late. 27/01 Growth is still going strong, it's still colder than I would like but it doesn't seem to be bothering her much. Thinking of adding a bit of co2 to my tent, a freind mentioned you can just buy some sort of baggies. If anybody has any experience with them would love some opinions. 30/01 Some great growth past few day's, she's looking much bushier and the secondary branches are starting to come on real nice! Tried to bend her over but think i've left it to late because she wouldn't budge without putting more stress than I was comfortable with. Both plants have started drooping 30 minutes before I switch off the lights and perk up again about an hour after I switch them on, haven't been able to find a definitive reason for this but it seems common enough and she's looking real good. Still gave me a fright first time I saw it though 🤣 Pretty sure she's just about to enter flowering pics in grow question. 01/02 Last day of this grow week and first sight of pistils 😁 seeing a speed up of growth also, the side branches in particular are starting to shoot up nicely. Should I start straight away with flowering nutes, carry on with veg nutes or I was thinking about skipping a feed just to clean up the soil a bit. Thoughts?
