HELP! LOOKING DROOPY

SOME OF MY PLANTS ARE STARTING TO LOOK DROOPY AND SOME LEAVES ARE STARTING TO CURL UNDER. THEY WAS GROWING VERY WELL THEY ARE STILL GROWING NEW SHOOTS HAVENT CHANGED ANYTHING AS THEY WAS GROWING FINE. THEY HAVE WIDE LEAVES THAT ARE DARK GREEN THEY ARE 8 INCHS TALL IN THE SECOND WEEK OF VEG. ONE HAS YELLOW PATCHS ON THE TOP LEAVES BUT I THINK IT WAS WHERE A LIGHT WAS TOUCHING FOR A LITTLE WHILE AND HAS SCOOCHED THEM AND SEEMS TO BE GROWING OUT. I AM USING 5 20 WATT COMPACT FLORS AND A 2 FOOT FLOR STRIP LIGHT. THE TEMP IS IS BETWEEN 20 - 25 C. I USED MIRICLE GROW POTTING SOIL. I HAVEN'T USED ANY NUTES YET AS THE SOIL HAD SOME IN AND I DIDNT WANT TO OVERFEED THEM. I AM WONDERING IF THEY ARE STARTING TO BE UNDER FED. I AM NOT TO SURE ABOUT HUMIDITY AND PH BECAUSE I AM A TOTAL NEWBIE. I HAVE BEEN USING TAP WATER THAT HAS BEEN LEFT TO SIT 4 2 DAYS . I WATER WHEN THE TOP SOIL IS GETTING DRY ROUND THE EDGES UNTIL IT COMES OUT AT THE BOTTOM IS THIS RIGHT? I HAVE READ QUITE A LOT BUT STILL NOT SURE ON EVERYTHING . ANY HELP WOULD BE GREAT THANKS

Hey, a couple of pics would be helpful mate. Droopy leaves can be caused by a number of reasons one of the most common is overwatering and it sounds like that may be your problem, you say you water when the top layer of soil is dry around the edges, the top layer will dry pretty quickly you should stick your finger a couple inches in the soil and when that feels dry then you can water, another method of determining when to water is based on the weight of the pot. An important aspect of watering is having the plant in the correct sized pot for it's size, it'll be difficult to water correctlly a small plant that is in a big pot, if the roots are only using the top 1/3 of the pot and you water untill you get water running out of the bottom it's gonna be impossible for the plant to drink all the water. Start of with small pots and repot them when the roots fill the pot, (at least 2 or 3 times throughout your grow)

Good luck!
