First time grower set up! Am i on the right path???

How soon can i start looking for plants sex???
Since i used feminized seeds, shoul i be concerned about sex at all??? could the temperature make these feminized seeds turn into male plants???

your only concern would be hermies... and im sticking to what i said the flouros shouldnt make it hot enouf for anything to stress your girls... im not sure bout flowering your plants at that height you wont get much from them.. from your first pic you look like you have enouf room for them to get much bigger and produce more bud for you... id wait a bit longer before flowering

Maybe ill let it vegetate another week or so! But at the moment im worried cause they are not growinh upwards, mostly sideways, with more and more new sets of leafs coming out! Is that normal??? Maybe too much heat??? I cant get it cooler than 30 degrees celsius!
These are some pics i have just made now!
Comments please!
Take care!

Maybe some preflowers??? Guess not yet!

I dont want to wait too much to start flowering, cause im afraid they wont have enough space to grow until harvest time. in total they have around 60 cm of free growing space! Is that enough?

time to think about your situation.. if you only have 60 cm of grow space and your plants are not getting very tall.... then i think your safe to wait until they at least 20 cm tall that way even if they double theyre size when you flower them you will still have some clearace for more growth... if you flower them now your not likely to get very much bud at all.. just chill and let them do theyre thing...

About the sex of the plants, i need to start flowering the plants so i can determine the sex or i can do that before flowering?
Could high temperature turn feminized seeds into male plants?

Would those 2 little things there male pre-flowers??? female??? or just a new set of leafs coming out?

It has been 4 weeks since the seeds sprouted! Too small for that age?
Maybe i shouldnt be smoking too much hash guys, i guess its making me a little bit too worried!
First time you know, sorry to be asking so much questions, but the books i have (by Jorge Cervantes) confuses me some times!!!

I can't see any male signs on those... Males usually stretch taller than females in my experience, and your plants look rather short. That doen't mean they can't show their sex later on. I would veg to 20-30cm, you can train the stalk to grow sideways while vegging (b4 flower).
