DAY 9. any advice? (PIX)

hey hey hey, todays the 9th day since planting. The strain is bogglegum, i have 3 plants growing under three 54 watt full-spectrum floros. ive been watering them with filtered water from a brita filter every 2-3 days (whenever the soil feels dry about 3 inches below.) I have two makeshift yeast-and-sugar CO2 bottles set next to the plants as well as an oscilating fan. I'm not planning on giving them nutes for another week or so. im also trying to figure out a way to increase ventilation and i really regret not starting with smaller pots. im using black gold organic soil and added a 3:1 ratio of perlite. right now the light schedule is at 24/0 but i plan on weening them to 20/4 soon and then possibly to 18/6 before eventually going to 12/12/.

p.s - one of those pics is on day 4 right after i watered. the rest were taken today.

ANY SUGGESTIONS? PLEASE HELP

plants are fine soil mix perfect light is right once they get 5 sets of leaves get them under a HPS and you'll be laughing

i was planning on keeping the same lights throughout the grow. would these not be good for 1 or 2 females (depending on my luck?)

does anyone have any input??

from what i read from someone here - theres no difference in weening them off the light then going straight 24/0 to 12/12.

what does the perlite give the soil?

perlite gives the soil drainage, and nah dont waste your time weining them, just go straight to 12/12 when you want to flower

thanks a lot, thats what i thought but a friend of mine said that if they are never introduced to darkness once until you try to flower them, then it will shock them when you do. guess not... any other suggestions for my setup??

yo i have one of the moisture/light/ph meter things but i hear those suck ass. i also have ph up and ph down but i dont know how to effectively use it. somebody please explain this to me. also, whats a hygrometer?
