[jimbooo]

no idea,

here's the details

I know that the Nutrafin Iron kit tests for both non and chelated iron - you could try one of them - about £7 though.

done. on the shopping list.

thanks for that, off home now so have a good weekend.

Ok, the Seachem people replied to me!
Here is their answer~

If the plants are growing more than you want you can cut back on the fertilizer and that will slow their growth down. Don't cut it out totally or their growth will show deficiencies. Also cutting back on the duration of light they receive will help too.

isnt laterite substrate supposed to be iron rich? maybe that would help.

 

[jimbooo]

thanks Utahfish but i have twice the recommended ammount of laterite in the substrate already. it absorbs minerals to give the roots time to use them, doesn't contain much in itself (acts like a nutrient sponge to keep them where their needed.)

Hmm, could that be what's sucking up the rest of your iron?

 

[jimbooo]

all sorted, i bought kent botanica "FE" on the weekend. much higher iron concentration than the multi nutrient fert i have been using.

all seems fine so far.
