I wonder if the plants need time to adapt to the changes?
but then again it's been 2 months?
they appeared to be doing so well ..then a changed in the set up.
Fast growing plants are likely to show nutrient deficiencies earlier. They're not sensitive per say, they just need food because they grow quickly.
Calcium and magnesium are nutrients just like the other stuff. In lower light settings your water source may have enough of them that you do not need to add anymore. In high light setups you're going to burn through them more quickly so it is something to check on if all other nutrient levels are accounted for.
Well...I can say one thing....my Belem is doing the exact same thing. 3+wpg, PMDD pre-mix (haven't switched this tank over to EI yet), Co2 and Phosphates.
All other plants in the tank are thriving beautifully.
Strange thing is that the 2 plants next to it are doing ok, but the one next to them are shriveled almost like it was left out in the dry sun and are drying out..?
My nutrient level are always in the perfect range for what I'm dosing and for the target range the last 4 times I check. I have checked right after dosing, end of dosing, tap water and a month later after dosing schedule.
KH: Tank water = 3 Tap water = 2 GH: Tank water = 7 Tap water = 7 Hard to tell what shade of green that I'm supose to be looking for.. PH: Tank water = 6.4 Tap water = 7.4
Could it be a PH shock to the plants when doing a 50% water change?
Maybe some plants don't like being dosed extra Iron from what is already in the CSM+B ?
