About two months ago I had to do a major trimming because my plant's leaves were doing what you see above in the pictures from today. I also double checked all of my ferts, testing everything you should and could besides one-off micros and potassium. I thought this was going well.
The problem has returned. The leaves either turn yellow with brown pinholes, turn translucent, or simply stay forming big holes and deteriorating away. The wrinkly leaves plant loses the leaves at the bottom as well.
Ph - 6.7 when co2 is on. Aiming for 30ppm co2.
Co2 - Checking on this today as I'm wondering if my trimmed plants are kicking into gear and using up more co2 than usual. 12 tetras, 4 badis, 1 pea puffer, 12 amano.
Kh - 9
Gh - 16
CA - 100 ppm
Mg - 8 ppm. Just dose more of this today and will test tomorrow
Iron - Hovers between .25 and .5 ppm
Nitrate - 20~ ppm
Phosphate - 3~ ppm
Potassium - Not sure because I can't measure it, but I've kept dosing potassium sulfate when I have no need to dose nitrate for whatever reason (feeding I assume).
Temp is 78 degrees all of the time. Light is about 50 par at bottom of 22 gallon long tank for 8 hours a day.
Potassium nitrate as needed. Usually don't due to blood worm feeding.
Mono Potassium Phosphate - At least 1/32 tsp a day because it will never hover over 2 ppm for longer than a few hours. Never hits 0 though.
Potassium Sulfate - I dose about 1/8 or 1/16 tsp on days I don't need to add potassium nitrate.
Iron and micros - CSM + B, simply aiming for an iron level between .25 and .50 ppm.
Magnesium Sulfate for magnesium. 1/4 tsp daily.
Calcium - Nothing since it's always crazy high from my rock.
What am I missing??? My only guesses are a sudden rise in the need for co2 (co2 injection amount has stayed the same) or too much calcium or potassium since I can't measure potassium or control the calcium. Something in my gut says it might be ccsm+b overdose too. Sometimes when I dose I *feel* like my plants start doing poorly the next day.

Something else that I don't understand is that my plants are bubbling like crazy today too. Ugh, why does this have to be so complicated? I added an extra dose of potassium and magnesium after seeing their state this morning,a nd also turned up the co2 just enough to bring it down to 6.6. So maybe one of those are to blame.
Ok wow. I guess I'll turn this into a nano log
My nitrate, which was at least 10-20 ppm this morning was around 0 ppm a few minutes ago. I believe the potassium or magnesium kicked something into gear big time.
I may have been a bit generous on my initial cac:mg ratios. I just remeasured after adding 3/4 tsp of magnesium sulfate and params are:
Gh - 15
Ca - 10 drops per https://www.plantedtank.net/forums/1...g-calcium.html
Mg - Must be around 5-10ppm now
