Your problem is nute lockout. You can feed your plant as little or as much as you'd like, but if the PH isn't correct your plant's roots won't be able to uptake the available nutrients and that'll cause the roots to burn resulting in nutrient lockout.

Get a PH tester, mix your nutrient solution and test it's PH. Adjust PH as needed and start feeding your plants again.
I'd come back and hit them with just a quarter strength nutrient solution at first though. If (when) they take that up with no problem and judging by how little of a problem they have taking up the quarter strength nutrient solution is how you can determine whether or to gradually and or immediately begin return to your normal feeding regimen.

From a cloud of smoke appearently, haha. I was reading in one of these threads that somebody said they didn't know what their ph was and was having problems, that's how. Upon rereading the original post must have gotten this thread mixed with another one.

I don't think those plants are close to being harvested either. "Flushing" is done by running 3 times the amount of plain ph'ed water (or you can use a clearing agent in the water) through each gallon of soil used. Plants being flushed for harvest should be flushed for 10-14 days before harvesting for a better finished product.
They look worse. They do not appear as if they have any sort of deficiency though. Looks like classic nute burn. I'd flush those suckers out for a few days to wash away the excess nutrients, tear away those fan leaves that are damaged and check the ph of the soil.

The amount of yellow leaves cause me alarm. The new growth looks good though. Seeing as how that plant is 3 feet tall and has just been recently induced to flower in a 3 gallon growing container concerns me a little bit. That plant is going to get a at least a few feet taller through out her budding cycle. As a general rule of thumb I like to give my plants 1 gallon of growing medium for every foot of above of plant growth. I'd consider transplanting that lady into a 5 gallon container (at least) for the rest of her flowering stage.

Yea, that's definitely a phosphorus ("P") deficiency. He said he noticed a few pests. I wonder what he used to get rid of them (if he used anything at all)?
He really does need to test his run off water or test his soil for PH. Phosphorus will lock out quicker than shit if the soil is too acidic or alkaline. An excess of iron and zinc will lock phosphorus out also, or yea, he isn't feeding frequently enough. He also doesn't mention anything about where he sources his water.
budgrowerwannabe, phosphorus deficiencies are easy to treat. Just lower the PH of your soil and water to about 5.5-6 and fertigate your plants with a complete and balanced fertilizer comprised or organic materials, or an organic or inorganic hydroponic fertilizer that contains phosphorus. Lowering your PH will ensure that phosphorus is now available to the plants.
If the problem is the PH being wrong in the soil it's going to be hydrated and dolomite lime tea time. The hydrated lime will go to work right away buffering the PH of the soil and is flushed out quickly. The dolomite lime will act as a PH buffer in the soil for a few weeks or so.

Test your run off water. Testing the run off water will tell you if your soil's PH is correct thus concluding whether or not you can simply begin feeding again. If your soil's PH is too acidic or alkaline, you're going to have some work to do.

Yeah he may be having phosphorus deficiencies but I'm sure the 65F temps are helping show a little purple on the stems. Plus the plants are stressed from the fact that he has had a insect wild life park in there.
65 degrees isn't really cold enough to cause purpling in the stems like that. Between 45-55 degrees ferinheight is the temperature fall coloring occurs at. Also, the blueish green tinge on those leaves is yet another symptom of a phosphorus defeciency. The insects MAY have caused a little stress to the plants. Stress to plants due to pests sure isn't evidenced by the pictures provided though.

30 years "under the lights"? Jesus Christ, you're an old fucker aren't you. 30 years is a few years under how long I'v even been alive. 
Yea, altogether I've been under the lights for approximately 6-7 years. I'm recently back under the lights after about a 4-5 year hiatus.
A little purpling of the main veins and leaf stems coupled with normal leaf coloring in a garden kept at 65F and below would cause me to accept that the major cause of the purpling veins and stems was fall coloring. I just don't know, man. From here those leaves look a little small in proportion to the size of that plant, as well as I think I'm seeing that blueish kinda tinge going down on those fan leaves which are two more characteristic of a phosphorous deficiency. If that were my plant I would investigate the PH of the soil to be sure there's nothing else going on, and if the PH of the soil was correct, treat the plant as if it were deficient in phosphorus.

I wouldn't keep that plant around. Especially if I had more plants from the same seed stock going on.

The stocks and branches are purple as hell and the leaf tips are starting to straight burn. Your soil's too hot.

Pretty sure, man. How trusted of a fellow are we talking here?
Correct me of I'm wrong. I'm just going by what I see in the picture. The younger leaves appear as if they are burning at the tips. That's a beginning sign of toxic salt build up. Another is the "tacoing" leaves. All that purpling of the main stalk and stems are a calmag lockout. I'd treat her as if she is suffering from toxic salt build ups and leech her - leech her good.

Purple stems do not automatically mean cal/mag. I've grown strains that have purple stems from almost day one. And they stayed that way well into veg. It can definitely be genetic.
That being said. It does look like your plant needs to be flushed.
Do you remember what the names of these strains you grew out that were all purple were called?
That being said - obviously purple stems don't automatically mean cal-mag toxicity or deficiency, as well as I'm sure you've grown these super rare crazy strains where everything including the stems were purple due to genetics, but we are talking about White Widow here.
When the purple-ing of the stems and main stalks is dark, all covering, and run up the veins of the leaf pedals plus "tacoing" leaves - it's a cal-mag issue. When the purple-ing is caused by a phosphorus deficiency the purple-ing is a red-ish purple, and doesn't completely cover the stems and main stalk(s). Phosphorus deficiencies come coupled with a blueish tinge to the leave color, as well as disproportionately small leaves in ratio to the size of the plant.
