Auto Bcn Critical xxl.. Newbie First Gro

Wow.. End of week 4 and they are still alive despite many newbie disasters. 1 nutrient burn despite only feeding quarter of recommended dose. = corrected (hopefully) 2 humidifier leaked all over the bottom raising the humidity to 100 percent... Found the girls drenched and drooping. I'll take the blame for not putting it back together properly.... = fixed (won't do that again) lol 3 location of tent means I am constantly having to correct temp and humidity in the tent.. Its either peeing it Down or 30°c outside. So the girls have been stressed by either heat rises or low or high humidity.. In terms of managing the environment I am getting into a rhythm.. I have 2 in room fans plus a 4 inch input venting external air into the tent, a humifier and also 2 x mini Air cooler fans with water reservoirs which I cool the pots with when it gets too hot.. It seems to be relieving some of the stress. The 3 beautiful Bcn Critical xxl ladies from Seed stockers appear to be coping really well, short, fat stems and tons of growth this week. I have decided to let the main cola grow and train the secondary growth into a star shape so each one is getting good light and they are all responding well... I think they are, however please comment and let me know your thoughts and any advice as although I'm quite proud so far, this is my first grow and feedback would be greatly appreciated.. Happy growing Ps no pistils yet but I'm thinking it might be soon as they are starting to stretch and I am getting faint smells when I open the tent ;)
