Am I burning these

Hi All
Me again I really do not want to mess these up this is my first time indoors or out. My Bro keeps telling me to leave em alone I killed my summer out door one got it in the house and burnt it up really not good ok enough rambiling I have ten going attached are pics I am using 1600 lumans cf lights 5 of them I was out of town and did not water them the dirt was like dust but they looked great so I then watered them came home tonight and they looked like the pics attached I have been leaving the light on 24x7 non stop watering once a day but today they are wicked droppy.... Notice the one in the back left hand coner I broke it in half when I light fell but is seems better some leaves are turning yellow though....
Any help would be great thanks and hope you are all staying :)

overwatering and lights are maybe to hot, u using a fan ?

Hey bro ... you might be over watering..I only water when 1/2 inch of top soil is dry ...Oh and the one broke 1 try to keep it attached to the other half might grow back ..(dont feel to bad my first grow i dropped a 400hps reflecter and everything on 4 nice 6 month old female's broke 3 and they ended up fine) also what kinda fert and dirt are you using ...And also can you put your hand at the top of the plant ...If it feels uncomfertable for you its the same for plant

Thanks
About 3 days ago I brought the lights down about 4 inches because It was kind of cold in there. Those CF lights do not give off much heat.
I last watered at midnight last night and I will wait till the soil looks dry
The soil is miracle grow from the wal mart....
It said it stops over watering more then likely why I have not killed them yet....
Thanks for the help
What is the best soil ????
Sorry to hear about the break on you buds the one I have did go back together just the leaves at the bottom seem to be getting yellow....
Why are they turning ????

ALso is there any types of nutrients I should be feeding them ????

For a first grower like i did i didnt use any nut's ..Turning yellow because over watering...I usally dont like using Mircale Grow ...Your best bet is to make your own soil when you transplant ..i got my on blend ....But usally just use organic shit cant go wrong with it
