First Grow Ever

No real issues with the plant itself so far, but since the heating has been turned off so the humidity has been all over the place, as well as the temperature. It would go from daytime temperature 25-27 °C with 40-50% RH to nighttime temperature of 18-19 °C and up to 75% RH. It has stabilised a bit over the past few days, ran a heater which helps increase the temperature a bit and lower the humidity. Also started very gently some LST, hopefully I'm doing it right. Noticed on day 25 that some signs of preflower are showing? Any comments would be appreciated to see whether I'm guessing it correctly! Will be going away for 5 days, thought it will still be looked after by someone else, but I'm worried anyway about the flower. Hence why I'm uploading an update so early. :P
