Aquarium plant deficiency

i'm skipping ahead
i know this is an old thread,

i've been looking for a bit now (not much because i keep getting distracted)

my plants are showing deficiencies, i'm at work most aquarium sites are blocked :( makes it hard to see what's going on here, ... yet i'm stuck infront of a computer for 8+ hours a day, lots of time to focus

anyway, to the point,...

plant deficiencies, ... as i red the start of this there is mention about balance (different words) raising one can cause other nutrients to lock up, i'm assuming PH issues which in turn could cause all kinds to lock up.

it's easy to find sites that talk about specific nutrient deficiencies, with pictures which helps ... great
but as mentioned, i could just dose whatever i think is needed and not be aware i am causing all kinds of other problems.

i can't quite call myself a beginner, but as was warned against just trying to jump to a quick fix, ... plant nutrient problems i might as well be a very early beginner, my plants are hurting and i don't know what to do :(

from pictures, ... possible calcium, but the tank is loaded with that, not a calcium deficiency in all honesty
possible iron
possible boron
possible magnesium
pretty sure there is a potassium deficiency (different symptoms)
as far as "possible"

pale leaves, the veins are yellow, the leaves of Hygrophila difformis are curved down at the ends (other plants the leaves are too small)

as i'm at work i can't post pictures, i'm lazy so i may not have them when i get home either, but finding time i would spend it looking at sites i can identify deficiencies easier, ... not that i don't like this forum, i do, the one thing i'm after is blocked at work :(

water parameters, ... (29 gallon tank)
ph is above 7.5, i need a high PH test kit, ... the PH is far higher than i want it to be
light, 4 T5HO 24" on about 15 hours a day, ... it's probably pushed the plants to the limits as far as nutrients are concerned

medium level of plants, ... i dono, people ask all kinds of questions about what is going on that i can't see how it relates, then someone else cuts to the heart of the matter and starts talking about what is going on & what can be done because the rest of the stats about the tank don't change anything about the steps to correct it.

not many fish, probably a tendency to overfeed , but dono really

i don't spend much time inquiring about such things, i am more content to search and find, ... but i'm really starting to worry about the plants ;(

I would be in favor of reducing the photoperiod to 10 hours. Maybe a CO2 deficiency/imbalance as is. I think the photoperiod is waay too long.

What kind of fertilizers are you using now?

fertilizers ?
none, ... not traditional fertilizers.

dried & crushed plant trimmings,
last done several months ago

couple issues going this method
-ammonia issue, can be resolved by letting it sit and run through it's cycle till nitrates remain
-tannis, ... bigger issue, ... from what i'm reading it's high in chelating ability, and at these levels instead of being beneficial it's a problem.

---

i don't know much about test kits & what they mean or don't mean

GH is 9-10
KH is 1

a low KH is it fair to say that's low CO2 as well ?

the lights are old & long over due to be replaced.

Short answer is "yes". A low KH means low CO2 according to CO2 chart (that chart ignore other buffers such phosphates). However, adding baking soda, will increase KH also pH, CO2 will stay low. I don't know if that chart has any value estimating the CO2 level unless you inject it into the tank

Here's a KH/pH/CO2 chart:



CO2 is inversely related to pH
CO2 directly related to KH (Carbonate Hardness)

My typical carbonate hardness (KH) is 3. If you let it get too low, as it goes out you could get the pH bouncing around because there is no more carbonate buffer to keep the pH up.

I think that more CO2 than the chart indicates builds up in the water at night and is used up by photosynthesis when the CO2 should probably run out

Low KH would reduce the CO2 level at any given pH level. I hope this has been at all helpful.

would this have any visual symptoms on the plants, or just slow plant growth ?

Thought this might help - my search string had 'aquarium' in it...does the chart apply?

Thought this might help - note that "Potassium Deficiency" does not mention pinholes, but CO2 is shown so this must be for aquatic plants.. Search was co2 deficiency aquarium chart.
