Although I may be seeing the rolling/crinkling in older leaves, it is definitely apparent in new growth. So, I’d focus on correcting for issues in new growth (immobile nutrients?) and let the older growth go, for now.
Possibilities (in no particular order):
1) Too little CO2 for a given PAR.
2) Too much Mn and/or too little Mg.. Reducing Mn, in such case, would obviously help. However, going higher in Ca and Mg may neutralize the effects of too much Mn. Given the above potential for these two discrete possibilites, I’d first determine my Mg level. Then, I’d try raising GH by 3 dGH, using a 3:1 ratio of Ca:Mg. If I saw improvement, I’d stop this extra 3 dGH dosing and, when the crinkling returned, I’d reduce Mn (which may be a part of a micro package) and see if this also solves the problem. This way, you may be able to rule in or out Mn and Mg.
3) K deficiency.
4) Leaf rolling is often a physiological phenomenon. Environmental factors like very bright light, a prolonged dip in temperature or a sudden change in water chemistry can cause the leaf rolling to express itself. If the water current is too strong, leaves will sometimes roll up.
1) Possible, this is my first time using pressurized co2. I am definitely just stumbling through it. I started low on the co2 and have edged higher over time. I am currently running about 3-4 bubbles per second in this 40 gallon tank. I have noticed no difference in my fish's behavior though I have noticed that if I either leave my lights on all day (instead of turning them off halfway through for 4 hours) or go much higher on co2 my drop checker turns yellow. So I have been leaving it where its at for the past week.
2) Can I test for this through just buying equilibrium or should I man up and buy some salts? I can get equilibrium at my local fish store, I think anything else I will need to send away for.
3) Could this be the case even though I am dosing with thriveC each day and I have dirt substrate capped with sand and sts?
4) I definitely have high light in this tank, but not brighter then sunlight the first picture is of a plant that I found in the wild in full sun. The other two plants are also wild plants but were found in the forest. Granted they were also emersed at the time. So I suspect if its light its a light out of balance with the other factors the plant needs. The tank is unheated in my basement, with only a few degrees shift its pretty much the same temperature. The current is also pretty sad in this tank, definitely on the lower end what is acceptable for a planted tank.
Easiest thing for me to test is to turn up the co2. After that its supplement time. I'm wary of gassing my fish of course which is why I have been inching it up over time until about a week ago.
