need some help for my plant. light is a problem

Hi, everybody, it's good to see you all in here.

This is my first time growing, recently i'm facing some problems that i really need some one's help.

Here is details,

9 plants under 2 nos 250W HID, about 5 feet higher above the plants, but i found the temp is going to high and the plants are getting fade, so what should i do??



These pics are before i adding the second light, anyone who can tell me how's plant like this.

And how much fertilizer should i put for one time, now i use around 2g with 1000ml water for the plant, is it enough for it?

if the temp is going to high get a fan moving some air around in that room, also do you have an exhaust? if not an exhaust will take alot of heat outta that room

thank you very much, could you see my photos, how would you think the plants is.

i have a small exhaust in the room, not enough to get all heat out of this room, and i got a fan for cooling but once i open it up , the wind will bring away the humidity a lot , it almost getting 35% humidy. Obviously it is not enough for the plant.

They look 18 inches tall,and those pots are small,you should flower them.

Thanks Mr. Ganja, these pics are the old ones before 4 days, i have change the big pots for them already ,

For the flower ,do you mean that i should change the light time to 12 hours, and use the HPS light. and do you thing 250W HPS is enough for 9 plants?

Another question is some of the plant is growing slow, around 10 inches high, if i change the light to HPS, if it will affecting the veg gorwing for them?

To be honest, i'm foreigner and this is my first time growing, so that i'm not quite experience for this.

So thank you very much for you all kindly help

The plants aren't getting enough light, and the pots are too small.

You should be able to keep the light at most TWO feet away without burning the leaves, meaning you should have good ventilation.

It looks like the plants have been growing for a while How old are they? The stems are thick. I'm guessing they are 6 weeks old.

Improve your room's exhausting capacity, lower the light, and transplant the plant into a container twice the size you are currently using good luck.

Thanks dudeoflife, you are right, the plant have been 42days around that time, as you said to low down the light to two feet above to plant, it will increase a huge heat , so i need a big fan for cooling , and a big exhaust if required to suck the air out of the room, am i right ? but the ventilation will take the moisture away from the plant , so that i need another separate humidifier for the humidity right ??????
