Plant Problem

Ok im new to growing but have done my lot of research before i started. I have 3 plants 2 in soil and one in a homemade hydro system similar to "fun with a 5 gallon bucket" on youtube.com.

The problem im having is with my plant in the hydro system. It has curling/drooping leaves, brownish and dark colored(almost looks likes routing), what looks like nute burn, and is much smaller than my other 2. i have changed the water and lowered the nutes but the plant seems to being a little worse. now its at a stand still. any suggestions?

here are some pics. keep in mind that they are a few days old so the plants are alittle taller, and the plant in the hydro system is a bit worse looking.

O.. and i have no idea the strain, i got the seeds from a friend out of a reg bag. im saving up for new seeds.

thanks

Uhhhh what IS that medium you have the "hydro" plant in? And what is the ph....you check it at LEAST once a day right? Has it been stable? And at what?

YIKES!!! :eek:
Probably a LEO posted that video to keep us from growing herb. That's garden bark mulch. NO NONONONO!!! Use hydroton pebbles instead.
In fact, hit that link in Weedhound's siggy and read it start to finish. Then read her other logs. THAT'S how to grow pot in a 5 gallon pail hydro system. For your dirt plants, hit the link in my sig, and read it all.
Never put more than 1 plant per pot.
