Fisrt grow looking for tips

Hi guys first grow here and looking for some help. I got theese clones from a friend that had given up on them and was going to let them die so there not in the best shape. There Nothern Lights that he got from attitude seeds, any edvice is helpfull since i dont know much. Ill update with pictures to see whats working and whats not. So what i got to work with is a 7x7x7 grow tent with a 400 watt light. I plan on splitting the room into a vegitation and a flowering room once i get that far into the grow. There about 3 weeks old since being pulled of the plant. I got them about 16 inchecs away from the light at 14 on and 10 off, also just bought a bigger fan to put in there. Im mixing 15ml per gallon of grow Humboldt Nutrients and switching between that and plain water every other day. Ill be going down to the hydroponic store tomorrow to buy some stuff for my next step ( i got 20 seeds im going to try hydroponics DWC ) so let know if i should be buying something to help me along with my first grow. Here some picture any help is appreciated.

when you go to the shop might want to get a bottle of HN's micros. Good selection on nutrients I have had some great results with their organic and A&B line. I would give them less than 15ml per gallon but I like to go really lite with my nutrients. give them some time and I am sure they will produce some nice bud! good luck and happy grow

thanks i will look into that while im at the store

Should i be chaging my light cycle to 18/6 pretty soon here?

I dont beleive so, it was an out door plant he said it was about 10 feet tall. I dont belive auto's get that big.

ya i dont think they do either...

Thinking about changing the light cycly to 18/6 any thoughts?

it is more useful for your mrBill
and there is no big differents 24 or 18/6

you mentioned watering every other day you will notice if you keep this route your leafs will start yellowing try to feed them like every 5 - 6 days
MJ likes dryer conditions

heres my girls i water 8 to 10 days

as for switchin to 18/ 6 thats a great idea IMO i would leave them on 24 hr lighting for a week then 18/6 for a week then slowly lowering your lighting hrs
thats what i do from clones on 24 hs a day to 18/6 for 2 weeks then 16 / 8 for a week then 12 /12

yeah you should switch to 18/6 the plants will grow alot more then in 14/10
do you have a fan vent for the light? how hot does it get in there?

So ive had them at 18/6 for about 2 months now you guys think there ready to change the ligh and light cycly to 12/12? The biggest one i have is 31 inches including the soil bucket and my smallest being about 26 inches.

Anyone have any edvice?
