I've upped the GH in the tank to eliminate any potential calcium/magnesium/sulfur deficiencies (using Seachem Equilibrium). I added 1 tsp per day, now it's been at 7 for the past 3 days (used to be at 4, but usually ran around 5).
Nitrates - Adding 10.9ppm per week (split daily) seems to keep the Nitrates leveled out around 15ppm.
PO4 - Still rising. I'm adding 0.3ppm per day, 2.1 per week. Somehow it seems to rise by about 1ppm per day. Looks like I need to further decrease this dosing amount, even though I'm already at 1/2 EI dosing.
I'm feeding my fish very sparingly, so I don't think it's coming from that. What is a reasonable about of PO4 to expect from feeding fish? I'm guessing this is still leaching out of my substrate from the O+? Otherwise I have no idea why it rises so quickly. Trying to do water changes to keep it lower (within 1-3ppm at least) and will decrease the dosing amount when I make a new solution.
I started CSM+B and Iron dosing at about 1/3 EI levels 4 days ago. It seems to possibly be slightly helping the deficiencies before (the dark/light veins versus tissue), but I think I need to raise it more. I'm seeing some iron deficiency as well, so will need to increase that. Currently I'm dosing 0.02 FE from CSM+B and .0179 from DTPA per day, but also added .21ppm through all the Equilibrium I added.
With all this though, the curling of my Ludwigia is still very present and doesn't seem to have changed at all.

Yeah, they are very very green for some reason, so is my ludwigia glandulosa. Its been in the tank for about a month has had almost no growth, and its totally green (see pic below)... and keep in mind I was dumping tons of iron in previously, along with CSM+B all at or above EI levels.
Here are some current pics.
Ludwigia still super curled:
Veins look to be improving somewhat after starting minimal micros back:
Rotala Wallachi is doing this for some reason. What does this mean? Its usually like this in the AM and will get better throughout the day. It used to grow very well (wayyyy back in the day before I started EI) but recently had pretty much stalled out and started dying off. It has been doing better after clearing out the O+ and after I initially stopped micros. Its turning a little green though... think it needs more iron? You can see it better in a pic below.
Rotala Macranda is stunting a bit. Maybe due to the change in GH? Maybe lacking micros and/or iron?
AR Mini is actually doing better than it has in the past... but still looks terrible:
This green plant in the middle is ludwigia glandulosa believe it or not, in front of my ammania gracilis. Gracilis is still doing terribly, no improvement in leaf twisting and curling, although it is turning a little more pinkish than yellowish. Maybe due to the lack of iron?
Rotala Macranda Green and Blyxa Japonica showing iron deficiency I believe. Rotala is getting light/white green, and new leaves in Blyxa are white.
So, that's where I'm at now. Unfortunately the leaf twisting/curling hasn't improved at all, and the ludwigias have no color, but I'm going to give it more time at the higher GH. I will increase micros and iron next week after my solution runs out unless it starts getting too bad without it.
