Leaves are beginning to curl and brown

I have had this clone for about 2 weeks in a garage boxed grow room.
Im using a simple Autopot (Auto Pot Growing System from Home Harvest Garden Supply) with a 125 watt 6500k CFL.
Tap water (didnt test for pH yet)
Worm castings soil mixed with perlite.
No fan circulation just yet, Im working on that next, but the box is opening up many times during the day for air and etc.

Before yesterday, the plant was in perfect shape no browing of the tips or anything. But then a few leaves were browning a lot and curling.
I wanted to know what could be happening that is causing this.

pH? overwatering? not enough air circulation?

Please give me any tips, thanks in advance. Sorry for big pics.

its just over feeding, you shouldnt be feeding that plant at all yet.
have you topped?.

Nope no topping at all yet. Topping is like trimming the plant yes?
Im new to all of this, no clue of the way to "top" the plant correctly and stuff.

Any tips that I should know for the next few weeks?

***also, in the second pic and last pic, the big leaves that are browning at lot, should those just be snipped?

i would just leave the plant for now,
i dont feed at all till after week 4 vegg, there is food in the soil, and after week 4 vegg i only feed 1 time a week till i get to 12/12.
if you want to top, cheak out the faq section, on fimming and topping,its easy ,if you need any help after that just ask.
you need a fan also, it helps rid the plants of there toxins, and makes them staronger.
what lights?
what cycle are you on?
and what are you feeding and how often?.

just snip off the dead parts, but dont forget a plants leaves are its solar panels.
just had another look, and has the plants got tears like pistals growing on the stem.
was this plant a clone, and where did you get it?.
did you have the mother?.

I havent gave it any nuits if thats what u mean by feeding it. It auto waters from the bottom up but when the soil gets dry up top i dribble some water now and then. i am planning on getting a fan asap along with a therm/hygrometer.
I have had it for 2 weeks at 24/0 and when I got it, it was about 3.5 inches tall with about 5 leaves in total. It is a clone and I do not have the mother.

It does have small pistils growing on the stem right now. The light is a 125 CFL 6500k w/ a brightwing reflector.

Can you see balls in the pics above? you are suggesting that it could be male?

in certain areas i see bulges, but im not no expert, prolly better to wait for one of the vets to come in.

Oh ok. I believe leaves are coming in those areas.

Also pistils and sex are supposed to be visible later on yea?
This plant at most is about 3-3.5 weeks old or so, I have had it myself for 2 weeks and again it was around 3-3.5 inches when I received it.

hairy muff, prolly aintshowing sex than.

with burnt tips it could be a number of things.first check the ph in soil,it may be a nutrient lock up,fungus,heat stress,over fertilized,im leaning more toward a nutrient def.( phosphorus)

it auto waters from the bottom up?you shouldnt water that way in soil!you should pour water on the soil to make sure water drains through the soil which prevents dry spots and allso it freshens up the soil to!
