Plants not growing!

Hey ya'll well I been vegin 9 white widows for like almost to months now and 3 out of those plants are growing at all. The 3 that aren' growing are 5" tall and the rest are 1' tall. Im growing in miracle grow organic soil. Im using Advance nutrients,ph is 6.5 , lights are cfl's floros and LED, and temps very from 85 to 104 yeah it gets hot here in socal. Friends say I need Co2 but I have no clue in how that works.. Sorry I tried uploading pics but I couldn't thanks..

WW is a bushy plant grown under good conditions. You could LST it

its too hot and u dont have enough light

sounds like the light and maybe to small for nutes

i bet its so humid that the plants cant transpire, and therefore cant pick up nutes

What's the size of the containers? Are they rootbound?

6 are growing on 3gal pots and 3 on 5gal pots. Will Co2 help me at all??
im was planning to use more lights because im growing on a 6x6 room and only have 5floro tubes 40w each. 4 giant cfl 100w each and 2 ufo Leds. I migjt need just a bit more light.

Are they healthy otherwise. When you have seeds of the same strain is doesnt mean they all grow uniform, some are just better than others. Pick out the best one and get a clone from it, then clone that and all plants should be be growing the same.

That sounds like a great idea. It could be my first cloning experiment haha. Thanks everyone for your help.

The heat will be why it stopped growing over 100 is way too hot! Peace

So if I control the temo will the keep growing?

Who knows, try it first and see if it works.

And the temps of 100 degrees fareinheight, thats like 37 degrees celcius i think of the top of my head! Too hot probably for a cactus!

Yeah id say your temps are too hot, if you cant bring them down much, might be smarter to invest in CO2, you can get a 20oz paintball tank for like 20 bucks, fills are usually pretty cheap, can get that at any paintball place too. Then you just need one of these

would almost be cheaper to buy a window A/C

Well I have a 10,000 btu ac running but cali is really hot right now..
I just noticed the plants that are growing are geting more light so im changing my lughts around. Thanks for all the help guys.
