Bizzare Golden Plant needs help ASAP

This is a White Queen plant that has some serious issues.
It's now 12" tall and in a 2 gallon pot with 40% premium potting mix, 30% perlite, 25% worm castings and 5% composted chicken manure with blood and bone, the same as the other 9 I planted at the same time, which are all fine.
I've tried epsom salts but no change, so yesterday I fed it some sulfer to see if that works, but I'm growing Organic and have never have deficiencies or major problems.
Lights are 3 x 200W 6400 envirolites with good ventilation.
I'm at a total loss, it keeps growing but now the growth is twisted.
I posted this several weeks ago but no help received.
Any help is much appreciated.

Looks like light bleaching. Well done.

Thanks, that's the only thing I can think of, but I put it on the outside of the lights for the past 4 weeks and It's only getting worse, and it gets less light than the other 9 of the same strain.
I have seen this before with Durban Poison but they fixed themselves after a short time.
Stumped.

Sulphur
Sulphur is an important element in the structures of amino acids and proteins, and is needed for normal plant respiration and metabolism of sugars and other compounds.

If you ever see this in your plants, then you can be assured that you have this deficiency. Look for yellowing starting from the top, and progressing down, including the veins of the leaves. Treat the same as a Mg deficiency.

Also they sprout yellow, if they sprouted new leaves green and then went yellow I'd be more convinced that it's light bleaching, unsure though.

Thanks for the reply, but as you can see if you re read my post is that I've treated it for sulfer deficiency, but no change.

Actually, it starts as yellow and then slowly turns green as it grows.
Sulfer deficiency starts yellowing at the top and works it's way down, which is different to what I've observed.
Same with light bleaching, if it was green and then turned yellow I'd be thinking along different lines.

I'll throw out a guess of severe iron or calcium deficiency, which is a required catalyst for chlorophyll production(explains new growth). I'd also add some nitrogen.

I have been adding some Green-Up which is a Nitrogen Magnesium supplement.
I use tap water which I leave in the sun for an hour or so and then earate with an air stone so haven't thought of calcium, and there are no signs of a calcium deficiency.
Maybe it's just a retarded plant.
Damn, after all this it'll probably go male on me.
I can and do mostly sort any problems, but this just has me stumped.
Thanks for your help tea tree.

Well, iron and calcium deficiencies both show up with new growth first, and lack(severe) of either can cause white foliage(which spreads!). Iron more so with the green veins and white intermembranes. Severe calcium deficiency and the entire leaf can turn white. Older stems usually are bright(deep) red, and new stems are pale and match the leaf.

Your plant will slowly die if it does not start producing chlorophyll. There are also bacteria that can cause similar symptoms(leaf whitening), but I don't think bacteria would really account for the new growth doing the same.

Things got worse for a while and now it's showing signs of recovery.
I've only added epson salts (magnesium Sulphate) and Sulfer Powder pictured in my earlier post. I also brewed some tea with worm castings and some organic fertiliser which has 2% sulfur listed in the ingredient breakdown.
The other nine plants from the same batch are all OK.
Sad news is it's a male so I wont be perservering with it anymore.
Thanks for the help guys.
