I have some Sunset Hygro which has been planted in my tank for about 3-4 weeks. When I got it, the tips were beautifully red-veined. Since then, the new growth has been coming out green, but having WHITE veins, and is shrivelled-looking. What am I missing/ doing wrong? Here's my specs: 100g tank, 260 watts c.f.'s, regular small black aquarium gravel with a layer of aquatic plant soil and laterite underneath. Flourish root tabs, Flourish, Flourish Iron.
Thanks in advance!

Calcium deficiency? As in maybe my water's too soft, and lacking in trace elements and minerals? (Unless calcium comes from somewhere else?) My kH is 9.5, and my GH is 22+, so, if anything, I think my water might be too hard. But how would I find out if my water's lacking in calcium?

Well, the one thing I haven't stepped up a notch yet in this tank is the ferts. Yes, I have 2.6 wpg, and I finally have co2, and I amended my regular aquarium gravel with a thin bottom layer of aquatic plant soil (profile) and laterite, but I haven't quite figured out how, which, when and how much ferts to use. I have been regularly (twice a week) dosing Flourish and Flourish Iron, and when I re-did the substrate a month ago, I added Flourish Tabs every 4-6" apart. But I know this isn't enough. I wish I had a recipe for my specific size of tank telling me when, how much, and which ferts I should be dosing.
I don't know what my co2 levels are. I'm sure not enough (2 1-gal. jugs are going right now. One through a powered reactor, and one into a diffusion bell. I'm planning on getting an in-line reactor like the 1000 really soon). I don't get any pearling, but all of my plants (except the sunset hygro) are strong and healthy, with NO algae.
Last time I tested my no3, it was minimal, but there was some (I'm guessing 10ppm? I'm not sure, I'd have to test again tonight to double-check). My P (phosphate?) was (I THINK) 0, but again, I'd have to check. If I need to start dosing p, I've heard that Fleet Enema is a good source.
Any other perameters you'd like to know? I might be missing something.
Thanks for your help!

Hmmm....it would make sense if the sunset needed higher light. Like most red plants, they need a lot of light, and I think what I have (2.6 wpg) is considered moderate.

Hi Dennis, thanks for the help.
Okay, I calculated my co2 levels: pH= 7.8, KH= 9.5, so co2= 4.517 ppm. Again, I know it's very low, even though I'm using 2 1-gallon (not litre) jugs, and I have a pressurized system on my list, but I can't afford it just now. Probably within the next month or so. I've only had co2 for about 1 1/2 months (and am still learning lots about it, and not to be intimidated by it!).
I forgot to explain my dosing schedule: Flourish and Flourish Iron- 2 capsfuls each twice a week. Not sure how much ppm that is, but it's slightly over what the recommended dosage on the directions are. I also have Tropica Master Grow (which you mentioned), but I'm unsure as to how much and when to dose. The instructions are very vague, and given in litres, I think. What do you suggest?

I'll test my no3 and p tonight. it's been a little while since I last checked.
As for the state of my plants and tank:
In my old tank, I had major bba and hair (thread?) algae problems. In this tank, when I first set up (1 1/2 months ago), i had a small bba and hair (thread?) algae problem, but, one by one, each kind has disappeared. I had a dusting of diatoms (brown algae) for a few weeks, but it's gone now too. The ONLY algae I have now is green spot (a little) on the back glass, and a few traces of hair (thread) on a couple of leaves of my biggest sword. But the ramshorn snails and otos do a really good job of cleaning up. My tank is (I would say) 80% algae-free.
I have tons of hygro (regular kind), which grow very quickly and lushly, several medium-sized and one large-sized sword, lots of val, several tiger lotuses, some red ludwigia, an ambulia forest (maybe a tad leggy, but still growing well), and lots of crypts all over the place. All of these plants are doing well. It's only the sunset hygro which looks like it's in trouble.
My fish load: I'm at about 1/2 capacity (if you go by regular stocking rules) with small (2") fish. Lots of platies, swords, some otos, cories, angels, and a pair of killis.

I didn't get a chance to test my no3 or p last night (laundry came first). But i did re-read through a couple of my aquatic plant books. One of them mentioned that the red version of hygro (not sure if they were referring to sunset, or some other version) requires a lot of extra iron in the tank.
That confirms what i had been thinking. Because, from what I know about plants, the red coloring COMES from iron (like it does in blood). But what I'm confused about is that i had thought i had plenty of iron in my tank already: I have a "first layer" or laterite, which has lots of iron, and I dose slightly over the recommended dosage of Flourish Iron per week for a tank my size (100g). And, I have other red plants (notably, some red flame swords, and an ozelot sword, and a few red tiger lotuses, which are all pretty red, although maybe not as red as they could be, or SHOULD be. But maybe that's still not enough iron, and I should be dosing lots more? Maybe I should buy an iron test?
