Something is seriously wrong with my plants..

[Jag1980]

Look at these plants, something is causing them to stunt, shrivel and die..? All my other plants are doing ok except for these.
Look at my Belem's. I use to have some of the nicest Belem's and now they are almost ready for the garbage.. :help: Any idea as to what can cause this problem?

Here's is one of the poor condition plants:

Here is the same plant growing next to it, it seems to be doing ok:

Now looks at my Belem's, they have been looking like this for about 2 months or so..

Here's a picture of the same group of Belem's a couple months ago, this is also what they looked like 9 months prior.
(This is 1 plant with 5 stems growing from it)

What has changed in this period? Feeding, lighting, etc?

 

[Jag1980]

Started with the Belem's after dosing Dry fertilizers with my green water issue.. Not sure when I added my Light fixture, but it wasn't too long before the Dry fertilizers.

N P K CSM+B Fe

Don't know enough to suggest any solutions, but I hope everything works out. You always grow such beautiful plants.

Thanks.
Things are starting to take a huge crap.

I'm thinking it might have to do with one of these:
Too much light
Fe dosing
Something in the CSM+B
Bacteria bloom or Green water having a affect on the plants

you've not said much about co2 - tell us about that - are you using pressurised; what ppm?

 

[Jag1980]

Green before I turn on the lights, very light green to yellow when I turn off the lights. Pressurized..

Too much light.

I"m leaning to light too. but did you test the water?

I have algae growing in my 75 now the only thing I changed was dry fertz.. I tested nitrate and it was high(80).. I did a large water change and am monitoring the nitrate
it didn't seem to affect the discus but I didn't want to chance it. I also backed off half the lights(4X65) now 2X65

a ten gallon needs 65 watts total - a twenty gallon needs 90 watts total

If this is your twenty - how many watts do you currently have? what type of bulb are you using? Is it full spectrum?
