Anyway you can tell all the parameters, substrate, exact lighting, and the exact fert. being dosed?

The lighting is just a home made light dome thing, it has 2 fluorescent power saving globes it in and they are 18W globes. I will have a proper aquatic fluoro box soon, my ex is making it for me but he has been flat out at work so hasn't had time. I have the dome thing on for about 12 hours a day and the jungle val has gone nuts since I put it in this tank. It's already grown around 9" to the surface of the water in only 2 weeks! I'm using Aqua Master Plant Food which is phosphate free and is "with Trace Elements" whatever that means. It says to use 5ml per 50L(13g) of water but I think I may have over dosed it a little recently. I forgot which day I'd last fertilised it so when I did a small 10% water change I re dosed with the weekly rate. Is it likely that this is the cause? I did a 30% water change today and didn't add any fertiliser thinking that may also be the problem so I'm going wait and see. The substrate is just regular tank gravel with broken sea shells mixed through. It's the same kind of gravel I had in the 15G and never had problems with the plants in that.
It says on the bottle of fertiliser that it eliminates the phosphate and includes high iron levels to help eliminate the growth of algae.
I have a feeling it is due to the bubble stone I had in there also. I knew it was a bad idea when I put it in there but thought it would be ok coz it was a small stone in a large tank. I'm hoping they don't die on me and give me time to rectify what has happened. I've grown accustomed to them!
Also just as a side note, a CO2 infusion set up is WAY out of my budget and a DIY one is too complicated for me. I'm hoping they will be ok with nothing just as they were in the 15G.
I've attached a pic where u can see the amazon sword and val. The sword looks ok in the pic but if u look carefully you can see the leaves aren't right.
Edit: Will add photo's soon, PC is playing up.
