plant trouble

i dont understand that well, but i think thats normal, you didnt see any growth because she was or maybe healing again, post a picture of your plant

I don't have a camera but I'lll do my best to get a picture somehow.
yes and lower leaves are allways droopy and the bottom leaves are turning yeallow/brown all the time since I started growing. I've lost about 7 sets of leaves already =/
after I found all leaves droopy the other day (It seems noone was opening the window actually, so I guess maybe ir was underwatered) I ferted it wiith some new fert I've got. I used a full solution of NPK 40-12-43, there is also writen that the fert has Mg, Fe, B, Cu, Mn, Zn, Mo. So I guess she shouldn't be lacking anything (or maybe P?). oh yeah, I ferted again with same solution a few days after.
maybe this explains the upper leaves curling up?

yes, see the fert must not be over used, just as the water, u have to give it like once a week, or once every 2 weeks, now, if the lower leafs are always droppy it might mean that your plant dosnt have enough light...
if your top leafs look fine, it wont die, but you need to give it more light

damn, some leaves have purple veins and it seams that it is about to start dieing again, I guess she needs potasium, or maybe it is locked up ? so should I get some high P fert or should I flush or just water or what ?

Those ferts your using might be the wrong type. I use an all purpose type 18-18-18 for vegging. I would flush the plant and lay off the ferts till it starts looking better.

Avoid cold temps as much as possible but dont 86 the fan coz you need ventilation. How big are the pots? What type of lighting are u using and how much?

Try to post some pics if you can.

slayah since it was only one plant, i would recomend you do the same thing DojaDave is telling you, the fan is ok, actually necessary and good for the plant to keep it strong, but if the wether is too cold and the fan is giving the plant a very chilly wind, it will get depressed.
Also im telling you, you should start to germinate a couple more seeds now, and start all over again, what u have learend so far!

good luck

well it's not getting cold air anymore, I am using 3x 24W CF bulbs(cool white(2x 6800' and 1x 5400')) is this enough for one plant ? yeah I guess I'll start to germinate other seeds coss I don't think that there will be something worth a smoke from this one, it's 1,5 month old ant looks like it would be only half of that time =/ still, I'll try to same this one, I'll flush it and try to get some fert which has more potassium. hey maybe there is some only potassium thing ? maybe there is some organic potassium feed which I could get at any store?

slayah look at this link at Overgrow.com:

See if anything there looks like the same condition :)

saying potassium I meant Phosphorus (P). sorry for confusion.

oh yeah, is it worth growing sativa at home ? couse it's the only seeds I've got now, the one I'm growing is a hibryd I guess.
