What causes amazon sword leaves to look like this?

Ok. I'll start dosing Trace separately.

Thanks everyone!

Yup it is not your lights. I think it sounds like you have a good plan. You need to dose p separately too though if you are getting 0. You should be seeing 0.25-0.5 ppm ideally.

Ok, I'll do that as well and try to hit that P level. Thanks.

Ok, I've been monitoring my P level and keeping it around .25-.5ppm. Now I noticed that I have more BBA. This seems to happen every time I dose P.

Some new growth looks healthy and some are warped. Now some of the old leaves are getting transparent. I hope I get this figured out soon...

i'm having the same exact problem and confused on what to do. started dosing a mmn mix ferts couple days ago. before that i was using the seachem line. still think im lacking something.

What's the minimum PPM that I should keep my nitrogen level for plants? My nitrate level is 10ppm and it's been 3 days since the last time I did a PWC. Nitrogen fert will increase my nitrate levels, right? Does it have the same effect(toxic wise) to the fishes?

10-20 ppm should be fine. Yes, it has the same effect, but it is not very toxic at such low levels. A lot dose for 20+. I like to keep N as limited as possible without bottoming out.

The swords are now showing N deficiency. Leaves are getting reabsorbed from the tip down. I'm guessing N went below 10ppm after the PWC last Monday. I guess I'll have to keep it between 10-20ppm.

New leaves are looking better. No warping or discoloration. So that's good news. It's one thing after another. It's kind of hard to balance the ferts. thanks!

Yup, always a challenge! You will get it eventually, and the work and frustration will pay off.

you can safely keep some rather large N numbers if necessary, so I wouldn't worry about it too much, but it's always good to just balance it out to where you still have a readable level prior to your next dose.

I should keep the N below 20ppm though with discus. I'm beginning to realize why it is better to have them in a non planted tank. With all the huge PWCs, you'll bottom out on something. I'll stay with my dosing regime and huge PWCs but this time I'll start dosing N to keep it above 10ppm. It never goes up close to 20ppm between PWCs. So my main concern really is bottoming out. Thanks!

I hope I'll get it soon. Lol
How fast does plants absorb P? How often should I test to check the level?

 

[fort384]

I would test it every week at least until you have it figured out. How fast they uptake it depends on a lot of factors... light, type of plants, availability of other nutrients and CO2, etc.

Ok. I will do that. It also depends as when plants get bigger and absorbs more nutrients than when they were smaller, right? I notice deficiencies when plants needs trimming.

 

[fort384]

absolutely - the bigger the specimen, the more nutrients it requires.

 

[roydooms]

Got it! Thank you.
