what causes pinholes in leaves?

[Freezekougra]

i'm guessing it's some sort of nutrient deficiency...i have pinholes in my sunset hygros

i only dose seachem flourish

thx

[abcdefghi]

I think that is a potassium deficiency. A quick search on Google and there are a lot of people with similar problems, almost all linked to potassium.

Woohoo my 1,000th post, kinda strange to think I have posted on here 1,000 times (not including GCC and Classifieds).

potassium

it always affects my hygros first too. it's how i know i've been slacking with my dosing. i think they are more sensative to K deficiency than a lot of other plants.

[Freezekougra]

thanks both and grats on ur 1000th post abc lol

i don't have any other fertilizer on hand right now, but flourish says that it has 0.37% soluble potassium. could i overdose the flourish to make up the lack of potassium?

[timwag2001]

i think it depends on what the levels in your tank are already.
i would think that you could probably get away with out any problems

[SnakeIce]

No, Because of the levels of the other micronutrients you would run the risk of getting toxic levels of those before you could add enough. K or potassium is the most common deficiency because feeding the fish gives you some of the other two macro nutrients.

[timwag2001]

if he increased the dose it would still be under the amount of csm+b from ei dosing, am i correct?

I don't even remember where I got this pic from to be honest but if it's yours then please let me know and I will give credit where credit is due

im pretty sure it's potassium
but the holes are bigger than pinholes and there's no yellowing on the edges of the holes

[timwag2001]

they start out as pinholes and get bigger. it's not always real yellow around the edge. you just see a tiny tiny bit on the outside of the hole.

[Freezekougra]

thanks

Grabbing a pin and stabbing your plants will also cause pinholes.

[chonhzilla]

Yay for potassium deficiency....


did it look like this?

now i think it's something else lol

the holes are nowhere as circular as the ones in the pic

i'll take a pic tomorrow morning, camera out of batteries right now

[dundadundun]

potassium or snails.

they're not always round or show any brown or yellowing.

Don't want to hijack the thread - I think this is on-topic.

This is some sort of sword I bought six weeks ago. Its been growing about a leaf a week. The leaf on the left with holes is new growth; the ragged one on the right is original (the plant was a bit battered when I got it). I have also removed a couple of leaves with extensive yellowing and browning - there is a little of that on a leaf in the centre.

Can anyone make a diagnosis? and maybe ID species?

(BTW, that photo of the java fern was helpful - mine used to look like that. I now dose macro nutrients, but not traces.)

Echindorus Bleheri. Looks like it needs some root tabs or Nitrates.

[tekonus]

And to think I always gave the credit for the pinholes in my plants to the bazillion MTS in my tank... go figure. That picture was amazing and I have saved it to my computer for future reference.

[bitbot]

Thanks, tanker.

[roscoe70]

Just for reference, I saw that pic at Aquatic Plant Central back in June of this year. It has been posted here before, the original was by a person with the moniker of Zapins. I too have kept it to refer to when anything unusual shows up. Thanks to the author and good luck.

CO2 is missing and from every other table, chart, image etc.
CO2 is a nutrient in the terms of submersed aquatic plants since we enrich it often times.

In agriculture, terrestrial plant, there is no CO2 limitation because the rate of diffusion in air 10,000 times faster than in water.

All those tables, images, examples are exclusively from terrestrial systems, and most do not apply since the levels are extremely high. It could be K+, but it could be CO2.

Plants will take old tissue and use it for new growth in aquatic plants more so than terrestrial species. Keeps algae off, closer to the light and surface(where there is much more CO2 available).
