Watering/Heating problems, neeeeed help!

i have a 550 ml (mililiter) spray bottle and a bout a month old plant in a 2 gallon pot, still in vegetative state... how much water should i be giving it everyother day? (in mililiters..) ...
also, my plant has rust colored spots on its leaves, and its leaves are KIND of curling up towards the light.. not too much. the closet stays around 76-79 degrees, but under the light its about 80-85 degrees... will this cause my plant to go hermie or male? i have 3 fans blowing in there at the moment, but theyre not doing much and i cant afford a heavy duty exhaust fan.. anyone have any ideas on what i should do? I didnt know growing a plant was so much work!:confused:

i should also say i have a 400 watt MH running right now at 18 inches away from the top of the plant... is that too close?

bump

18 inches away is fine as long as the plants dont get to hot, the closer the better up to about 12" away.

water when the soil is dry, theres another thread near this discussing the same thing.

85 is a little warm but not to bad.

cool man, but how much should i water it when its dry? like 50 ml? thats about how much i give it every watering, if that

its hard to say, it depends on soil drainage, plant type, heat etc.

if the leaves are looking good then its ok....it sounds about right for a smallish plant, matbe a bit more, its water needs will increace as it grows though.

500 ml should do in that size pot should last 2/3 days in them temps

awesome, thanks guys

WATER TILL IT STARTS RUNNING OUT THE BOTTOM.

and that wont drown my plant?
