Basicly I want to know why my plants are waffeling. THey all seem to do it and it has stopped plant growth almost entirely. My amazon has a kinda of bending waffely leaf and has transpanrent spots on some leafes. There is also some dark algea growing on most of my plants edges and it is imposible to get off.

What fert am I missing.

I think its my Nitrates. THere only at 2-4ppm but everything eles should be all good I mean I dose iron everyother day and micros twice a week

PH-6.8
GH- 4
KH-4.5
co2-15-30
nitrate- 2-4
ammonia-0
temp 82 "discus tank"
w/c twice a week

where is your K+ and PO4? dosing any?

K+? you mean KNO3? Whats PO4?

K+ is potassium, often from KNO3 or K2SO4. PO4 is phosphate, often dosed with KH2PO4, or fleet enema.

Yes I have some kent phos in hand but I have no reason to use it with such low nitrates. I am tring to get ahold of some KNO3 but, just can't find the stuff at any LFS.

Doubt you will find KNO3 at LFS. Try hydroponics store or a pharmacy might sell it to u. Also www.gregwatson.com is the place alot of americans get it from.

Hi tiptoptank!! I am having a similar situation going on in my aquarium. I have a HUGE Amazon Sword that has been doing very well. Recently, however, the new leaves haven't been growing nearly as long. They were hitting nearly two feet long a month ago, and now they are only making about half that. Many of the older leaves are getting the transparent spots and the oldest leaves are starting to waffle. I haven't been dosing or testing recently.

Please enlighten me: what is a "waffled" leaf??

I fixed the problem! I started adding about 10ml of potasium, And alittle more phosphate. Problem solved. I didn't have to wipe the glass down as much either since there was no algea on it.

that's great

Is green dust algae caused by low phosphates or something?

I don't know if it is CAUSED by low PO4, but after adding high PO4, green dust disappeared along with green spots. Unicellular algae (causes green water when it blooms) also virtually disappeared from water column. My pre-filter sponge used to turn dark brown/green when I wash it, now it is pretty clean apart from some plant debris.
