First Grow -- Light spots & some curling on leaves

This is my first attempt at growing pot. It's a tiny plant with only 2 sets of "real" leaves so far. But the older pair of leaves are starting to look sickly. They have some light spots and look ragged. The younger pair is a little curled. Here's a picture:

Anyone know what this means?

12-18: Fed it 1st 1/4 strength nutes after first pair of leaves looked like this:

12-20: Fed it 2nd 1/4 strength nutes after 2nd pair of leaves looked like this:


12-21: Fed it 3rd 1/4 strength nutes. Plant looked like this:


I'm using Advanced Nutrients products. 1/4 strength nutes in my 3 gallon reservoir:
11 ml Sensi-Grow A
11 ml Sensi-Grow B
6 ml Voodoo Juice
6 ml B-52

I'm feeding it aerated water + nutes through a tube from above as you can see in the photos.

Went downhill fast since feeding third 1/4 nutes. Am I underfeeding this plant? Maybe overfeeding? Something else going on here? Any advice would be appreciated. Thanks.

I'm no hydro expert, but they look way to small to be feeding them anything.

Good approach!

Off the bat, save the nutes for later. Belive it or not, this benig your first grow, you should practice patience and not bringing this up to anyone that is reasonably worthless to tell. I dont mean to come off strict, but as of now, the approach should be to get a good basis of growing. And seeing if you can keep your mouth shut. The jail house is no place to talk yourself into changing you ways. But if you're cool about this, you can be the man one day.

Stay as constant as possible. Become familiar with the foundation of growing and trust that with just the basic approach you will gain valuable knowledge and nugs. Having a good start is the most important thing and by staying care free after the plant has began its own life is the key. It will reward you for giving it life, so when the time comes, feed it, but until then stay off the plants with the chemicals. I have smoked very worthwhile stuff that grew straight off of the water from a hose. Nothing more. If you have the vibe and the lights, your plants will return the attention. Be sure you read about the processes and start very broadly. dont get very focused on one part of the grow or from one person's advice unless they are authors or creditied horticulturalists/botanists. Like stated before, this is way too early to feed. This is like taking a baby to the tanning bed-

Stay real and start small no matter what. Read, read, read, and gain the universal knowledge about the light spectrum, plant processes, and stages of growth before adding space age fertilizers. If you can, keep this grow as basic as possible and just keep clean and safe, learn and burn. Let this plant know that it is the leader, and let it fight for itself. It will succeed, and by letting it teach you, its sisters will reward you down the road.

Keep it up, I'm ready to follow this into the new year!
