If your new to EI you can simplify it by looking at recent thread by@EA James "Will APFUK state kit suit my needs" and answer by
@X3NiTH .Is a formula many of us use
Tanks I just read that tread, and I am kind of in the same boat as EA James! A bit confused about what to add more or less of. I even don't have a water report.
Are they the new or old leaves?
I Think mainly on new leaves. They don't look as bad as the rhododendron... something like the leaf top left corner. Will post pics when lights on tomorrow.
But I had this problem for a while now. Why I also see this in older leaves.
I think your suggestion of an Iron deficiency is most likely. As it has help after I started giving the correct micro dose of 10 ml. This I have been doing for just a few months. Before I was only dosing 5 ml. by mistake.
Before that I was dosing the same amount of macro salts but as a All in one mix. This was with even less rexolin apn as the micro part.
Then Zeus asked in the forum for an alternative for micro concentrates, and after my suggestion of rexolin apn he was kind to a calculation. Unfortunately I started dosing my 100 l tank like it was a 50 l. This was still more micro in the water than before. So my micro dosing have been stepped up to reach 0.5 ppm iron over... hmm... maybe 6 month.
Maybe I should continue to see how this will go with consistent dosing and weekly water changes?
Must admit I have been busy and lazy in periods with 6-10 weeks between WC. Yeah, shame on me!
In theise periods I stopped the daily dosing at some point. And just dosed 1-2 times per week.
ok, 10ml of that in 100l gives
14ppm NO3 Recommended 20-30 ppm
1.9ppm PO4 Recommended 2-6 ppm
17ppm K Recommended 15-30 ppm
3ppm Mg Recommended ???
My iron dose is 0.5 ppm
Recommended 0.5-1ppm
I found recommend valuea here:

When I compare this to the recommend ppm for EI I get your point... it is not that of, but in the low end of the range for the ppm target. (Not thinking about values in my tap)
Should I adjust or stick with consistent dosing micro and macro on alternates days with the weekly 50% WC?
I don't think you can dissolve that much of each into 1000ml.....
You might be right, I have a 0.1 g weight so I ad salts pretty precise. Anyway when I made it as a all in one mix, it was with a little precipitate.
After switching to a micro and macro mix a have not seen the macro mix with precipitates. Anyway it might be at the limit of solubility.
Thanks a lot all of you... this forum is the best place to spend time of duties!
