signs of defiencies

[sonique]

i notice some of my plants are a little yellow and the tiger lotus's stems are kinda weak and the leaves a little frail wif green patches instead of red and soon may develop holes in it....is it a sign of potassium deficiency??? will dosing of KNO3 helps?

Might be any nutrient. If you notice the nutrient deficiencies at Chuck Gadd's website are almost all generally the same or interlinked.

What are you dosing right now?

i've read chuck's website, tats where i came to seek further help here....
its stated tat lack of potassium leads to pinholes appearing in older leaves, and slowly enlarge,yellow areas,withering of leaf edges and tips...pinholes tat slowly enlarge is seen in tiger lotus, slight yellowish is seen in nanas.....

i'm dosing seachem flourish and seachem trace....
according to the seachem website, the trace is dosed every alternate days and flourish is dosed twice a week...but i dosed both every alternate days but in small amount, about 2-3ml to 80l of water(2ft x 1ft x 1.5ft)...

and the content of iron and potassium is rather low compared to LGA and LGM (mayb i'm wrong?)....mayb thats why they have seachem potassium, seachem iron in individual bottles...??

Maybe u wan to try other micro like TMG, easylife, Dennerle, etc? Do a search on the contents of the brand u like to use and decide.

I feel that Seachem's stuff is too diluted. You can safely overdose by twice the amount imho.

If you think it's a potassium issue, you can buy Seachem Potassium and try dosing.

You're only doing Seachem Flourish and Trace. I believe there's not enough macro nutrients (nitrogen potassium phosphorus if you don't know) available.

As a shortcut, you can get Ocean Free's Root Monster and plant a couple of the tabs near your Lotus. Once a root hits the tab, you can expect your Lotus to grow like there's no tomorrow. I'm not speaking from personal experience, but from numerous testimonials for lotus's growth with respect to Root Monster.

Does your lotus pearl intensely? It should with good CO2/light and nutrients. The issue is likely from lack of macros/poor CO2 or both. Nutrients are easy to rule out by dosing the EI method. All that is left is CO2. Light is pretty straight forward as long as you have enough intensity.
