WHY ISN'T IT WORKING?!?!?!?!?!?

DAMNIT!!

Every time I start a plant it starts off great. I sucessfully germinate it and as soon as the vegetative state hits week 2 then everything goes to shit, and I mean SHIT!

Ok here is my situation. I am growing hydroponics. I use the basic General Hydroponics line of nutrients, Grodan woolrock, and a standing bubbler setup in a 3 gallon bucket. I have 4 45 watt compact flourecent bulbs that emit 2600 lumens each. The Ph is stable at about 6.1. I have air circulating in the room.

I can get past the germination phase. However once I am past the germination phase I can't do anything. This has happened to me over 7 times in a row and I can't get a good diagnosis.

This is what my most recent failure looked like. Other times it has looked like other deficiencies.

I have the Indoor Bible by Jorge Cervantes. I have been reading and reading and reading and I can't find anything that I am doing wrong. My setup seems decent and everything seems to be going great.

This most recent failure happened like this: I come home from work I go look in my grow room. My plant is in the second week of the vegetation phase with about a total of 4 full grown leaves, but it has these brown spots developing on the inside part of the leaves. I immediately run and changed out my hydroponic solution adding more nutrients to compensate for the deficiency. I have everything all done and setup. I leave for school and I AM NOT KIDDING YOU, 2 hours late I came back home and looked at my plant again. IT WAS ALMOST COMPLETELY YELLOW!! WITHIN TWO HOURS!!! WHAT THE F*-**!!!

Has this happened to anyone else? Am I just cursed at growing?!?!? What is the big deal here???? I have grown other kinds of plants and I have never ever had this problem!

Should I just go back to soil growing or something? What should I do?!?!

check your nuets. it sounds like that one other thing that all your grows have in common is yor nutes. check that you arent mixing them in the wrong order if they are three part nuets i beleive that there is a specific order that you need to follow or maybe they are contaminated. i use a 7 9 5 1/2 tsp. per gallon of distilled water @5.7-6.0 ph. for the first seedlings after that use i 1tsp. of 10 5 5 per: gallon 1tsp 7 9 5 per: gallon and 1 tsp 3 12 6 per: gallon i use a three gallon resv. change out every week i use nutes to adj. my PH every other day and distilled vinegar to lower it (both of these lower PH. the reason i use nutes to lower my PH is because i only use 1 tsp. of nutes per: gallon to start off with so when i use nutes to lower my PH i wont over fert them i dont know man works for me and my plants very well!!!!! no one told me what to do i kinda of just did some research and came up with those mixtures o yeah my nutes of choice are dyna-grow and superthrive and some co2

when using RW,you want the pH around 5.5-5.8,check the temp of the reservoir or bucket,should be 65*-70*fh,for seedlings use 1/3 of mix of full dose,always mix the micro first,then add the others....bonbon
