For CSM+B you'll see dosing ranges of 5-10g:1L dosing 1ml/2L column or equivalent. The idea is basically to lead with the strong iron content; add .15-.3ppm a week. Some of us are pushing higher now; I've been doing .3ppm dose for a .6ppm max on EI, Tom Barr has headed up to 1-2ppm dosing. some of the newer papers are showing hydrilla sure loves the stuff:
Absorption of iron and growth of Hydrilla verticillata (L.F.) Royle

Crypts seem to suck the stuff up, as well as other plants. When I've looked at the LC/LD50's for the fauna, I can't see any harm coming to them at elevated levels from the usual .1ppm suggestion given in older dosing methods, and the sort of Fe you can expect out of TMG/TPN or Flourish.

The down side of course is getting shorted on some of the other micros/traces that are hard to get in a water report. That, how ever, seems to be covered with your trace rotation

mrkookm, I find it interesting that you've been the one advising leaner Ca/Mg dosing through the threads we've overlapped on; I keep my Ca/Mg/K+ about 20% lighter, but in reasonably similar ratios. What gives?

Texgal I suggest that you also relax on the N&P dose. Try 1tsp 3x week & the PO4 to 6~8ppm for the week. You do not need 40+ppm N + 12ppm PO4 using aquasoil + fish load

Leaner CA/MG as you call it I found out a long time ago worked well for all the plants that I keep even at 0~.5KH, so i just stuck to what worked. Plus I also like knowing TDS is on the low side.

I put little emphasis on the optimal 'ratio' but rather the optimal level where my plants are happy. I essentially tried varying CA levels starting from 1GH up until all my plants were happy + some just to see how far I could go, the same with Mg. So when I suggest I am not guessing ...I'm sure you did the same thing

When I dose leaner N&P I get melting Erio III and stunted growth in Ludwigia senagalensis. My red root floater stops growing. It might be my imagination but I believe the my Rotala sunset and Nesea pedicilata, gold begins to have issues as well. I really think I need to keep the macros where they are.

Disregard my previous suggestion maintain your current NPK routine.

I began dosing my traces everyday as suggested by Reasheed. I haven't switched to different traces yet. I didn't mix them yet. All I did was take my original dose of CSM+b and cut it in half dosing it every day. Along with that I am dosing the Flourish Fe 10 ml everyday.

What a difference!! I see no stunting in any plants. I have the largest leaves on my L. senagalensis I've every seen. My P. Kawagoeanum leaves are longer (now I see the difference). I'm getting even deeper color. My L. glandulosa has taken off! (There's more but I'll stop there.) I'm amazed!

I'm going to change one thing at a time so that I can learn cause and effect. I did get the iron from Orlando and TNP. I'm trying to finish up the Flourish Fe first.

So let me understand this - what you did was take the full amount of micros you were dosing throughout the week, and divide it up so that it would be added daily instead?

You're adding these on the same days as you add your macros as well? Different times of the day, I assume???

Tex Gal

Almost.... I took the EI dosage the CSM+b for T,TH,S and cut a daily dose in half and am dosing that every day. So that means I'm actually increasing the weekly amount by 1/2 of a daily dose since I am now dosing on Sunday too. For the Fe, I'm adding the full dose every day. I add the macros in the am and the traces in the evening.

I do almost the same on my 125g now, but I still dose 1/2 tsp CSM+B 3x a week, plus 20ml of TPN 1x per week on the off day. Traces in the morning, N,K at night. I'm still finding I have enough P where I only have to add once per week. I expect that to change shortly though as the tank is really starting to "get into shape" since I've increased my traces. Getting a new light Monday, and I suspect my HC and Glosso problem will be cured as well (growing, but more up than anything).

Tex Gal

I stopped dosing extra K about 2 months ago. I found that I was getting stunting on some plants. When I stopped the extra K those plants' stunting stopped.

Bryeman

Not me, basically because I'm not having to add P yet (or not often anyway). I'll stop when I add both N and P on a regular basis. I still have a few plants with pin holes yet. I'm not over doing it either though. Just replacing what I would be putting in the tank if I dosed KH2PO4 more often. Plus, my Cabomba is growing 2" or more a day. Stunted growth may not be a bad thing!
