Need Help Quick! It's Dieing and I'm clueless!

Hello there!
This is my first set up and I am having a problem with the clone i got a month or so ago. It was first in a smaller pot with soilless grow, but was transferred to a bigger one with even more soilless stuff.

Set up is a really nice closet tent about 4 feet tall and a foot and a half both length and width wise. Light is a 150watt Sun System. Three small vents near the plant with a desk fan circulating above the hanging light. The zipper door is open so a bigger fan thats blowing outside can keep it cool. It's at a constant 75 degrees.

Problem: wilting bottom leaves, yellowing leaves with brown tips, dark green veins with lighter colored leaves, some leaves are really dark green

We water with nutrients every 2 to 3 days.

We have some type of nutrient defiency but I dont know which it could be. The symptoms fit the descriptions of nearly all the deficiencies.

Just in the last day it has gotten much worse than the pictures. We now have more brown and there is a hole in a leaf.

HELP PLEASE!

What nutrients are you using? You're right you have a deficiency, you need to up the strength asap.

Double your nutes. A couple drops of superthrive will also help them recover from the stress. Use it now and whenever you transplant. I think it will bounce right back in 3-5 days Let us know how it turns out.

Save this link and smoke a bowl my friend, your plant is not dieing as much as you think..........................http://www.greenmanspage.com/guides/plant_abuse.html

What's the ph of the water you are using? Looks like a ph issue.

everyone above is on the right track. nute are off and ph is well who knows.
they can recover in time.
greenmans page is good FREE info.

Recipes for success kit by technaflora. I doubled up the nutes with boost, grow, and thrive alive, and double checked the ph. Thanks a lot of the comments and sorry about my less than hasty response. It already looks better. I started it on 18/6, and will post pictures soon.
