2 weeks old plant problem..

Sounds like you overwatered. A good rule of thumb for any potted plant is to water every other day or so. You want to allow the new roots of the plant to get oxygen as well as water. As the plant gets bigger, you will water less often but larger amounts each time. The root system of a larger plant can hold a lot more water, so it doesn't need to be watered as often. Never fill the plant with water until all of the dirt is completely saturated. Hope this helps, I am a beginner myself. Don't stress the plants are young and will recover.

Thank you, all advices are welcome and i will keep this in my mind.

I have a quick question;
These are my box dimensions :
W: (14.6in)
D: (22in)
H: (28.3in)
so how big can i let my plant grow before i turn 12-12 without LST-ing or
any other treatment, i'll learn that later, first i want to learn the basics
of growing?

The plant is ok, she is getting better and there is no more sings of browning(the old browning stayed),
she is a bit overwatered now so i will leave her for a few days unwatered.
Thank you guys.

can anyone pls help me, now it seems i have a different problem, can someone tell me what this is and what to do???

Yep transplant into nute free soil and water, but don't over water, you may get root rot! Good Luck.

well i dont have any nutes free soil, can i try to flush the soil and then transplant in to that soil, whould that work?
And another thing, the problem right now isn't the brown leafs but the culring up, the browning is there a couple of days and it stopped spreading, so im was asking about the curling up??

does anyone know what does leafs curling up mean, and what can i do about the problem?
I would be very grateful for advices!
EDIT: I think i was heat stress, i've just moved the lights a bit further so i think it will be ok.

Hey guys, i was wrong, the leafs are still turning brow despite the wood ash-water solution.
I just found some nutes in a fluid form for foliar feeding, here is what it contains:
N(in amoniak form): 18.000
N(in nitrate form): 39.000
N(total): 57.000
P(total): 13.900
K(total): 23.900
Ca(total): 14.200
Mg(total): 1.800
S(in sulfate form): 6.000
Fe(total): 90
Cu(total): 85
Mn(total): 56
B(total): 52
Zn(total): 21
The packaging comes in 10ml and it is supossed to delute in 1L(o.26galons) of water,
i used less than a half of the 10ml for 2L(half of galon) and sprayed on the leafs.
I still dont know what the result is going to be but i was wondering about ur opinion about the nutes, is it any good?
P.S. i translated the content of the ferts so it is a bit off but i hope you can understand.

anyone has an opinion?

NVM, i got the answer.
BTW the plant is still alive but lost alot of leafs, i had to remove it from the box, it turned out there wasn't enough fresh air,
im fixing that issue right now and i will report with a few pic's of the plant when she gets a little better =)

leaves curling up might be heat stress it happenned to my plant i had it in a box too and it was getting too hot . i also had alot of tinfoil all over increaseing the heat. let it get fresh air and some water

Yes, i came to the same conclusion.

Well now she is getting MUCH more fresh air and the temps are lower.
No more yellowing or browning of the leafs; same soil and still using water-woodash solution but i added some foliar nutes and i spray her every now and then.

I'm thinking about LST-ing, alltho i didn't even know that it can be done with cfl-s.
i went to do a little research and saw that peaple use LST-ing with cfl-s and successfully so im thinking about it, it could prove to be useful.
already tied her down at the biggest set of leafs and expecting the results.

changed my mind....i'll leave it the way it is, since this is my first grow and it is proving to be a bit more complicated than i thought.

hy guys, just to report.
I just dont get it, the moment i put the plant into the box she starts to turn yellow and brown and when i put it on the window the plants stops, so i know it isn't the soil but i have very good ventilation in the box, i can keep the temps very low but that means that the fan will be intakeing the from outside and it is pretty cold out, so i dont know how would that work- heat from lights and very cold air blowing into the plant. Plus i was wondering can alot of smoke in the room where the box is hurt the plant if there is no real fresh air? By alot smoke i mean a box and half of cigarettes in a bit smaller room?
Im running out of ideas, any advices on the subject??
Thanks for all the help so far and ill get some more
Peace

i just wanned to let u know that my baby is alive and well & here's a pic to prove it..just so u don't think i killed it
She is now on a window ledge and doing as well as she can since there is very little sun but it is getting better, she(i hope) will go outdoors and grow any was she wants to.
I still dont know for sure why she couldn't grow in the box, but im 90% sure it was lack of fresh air, i will work on that.

i finally got some nutes, for growth i have 15-5-7(NPK) and for flowering i have 15-5-30(NPK) what do you think?

Alive & doing well, in abouth a month maybe less "she" is going outdoor.
