Undergrown?

This is one of my plants, it is 5 weeks old. I don`t know but she looks rather small. The soil is 60% earth and 40 % sand. And recentlly it started to yellow on the bottom leafes more and more, these ware taken last night but this morning it was worst!!! Is that natural? I don`t use fert.
Please help me out, gimme some good advice.

What type of lights are you using? How many watts? Plants will grow at different rates depending on, how much light, the type of light, if it's a soil grow or hydo ect.

neons 72w( total power) but today i will install a 400W MH

They look ok to me. Just small. With that light you need to be one inch or less away. I usually let mine touch for a week before I raise the light. The lower leaves may not be getting enough light. They could of been damaged earlier in life and are giving up. Could be a nutrient, nitrogen. It doesnt look like a big problem. The plant looks healthy over all. You are going to see some nice growth with that 400w. Throw up another picture about a week after you changed lights. The first day I would set the light about 24 inches away from the tops. Drop it to 18" the next day and see if you can get it close to 12" or less in the next week. You may not have to move it much since the plant will grow to the light. Just figure out where it starts to burn the plant and keep it a little higher. Pretty much as close as you can get before it burns.

Thx for the advice, i will take before and after pics and post them, i`m so curious about how the plats will perform with the big light What should the temperature be at the top of my plants? u know what i mean ... i hope. In my grow closet the temp is 26-30 celcius.
Please tell me ... btw i don`t use any nutrients or fert yet.

85*f......

U need to keep an eye on that temp if u go over 30º for a long period u may have some probs...the temps should be 20º (night) and 26º (day - lights on)
