I'm using 100% RO water.
2 Years Old Aquasoil substrate
Current water parameters:-
pH - 7.6
GH - 1 dGH
Ca:Mg - 4:1 (Only during Water change day using CaSO4 & MgSO4 on replacement water volume)
KH - ~0
Pressurized CO2 at 4 bps.
Tank water + Sump = 440 Liters.
Tank dimension : 4 Lx1.5 Dx2.5 H ft.
Weekly 25% water change.
Light: LED 220w, 20000 Lumen at 4000K
Weekly Dosing:
Nitrate - 40 ppm
Phosphate - 2 ppm
Potassium - 30-35 ppm
Plantex CSM - 0.1 ppm registered on Iron
Some plants are stunted, tiny leaves and almost 0 growth tops.
Suffering plants are Rotala Rotundifolia, Ammannia Senegalensis and Gracilis and Alternanthera Reineckii Mini (Showing Reds but tiny top leavs but stunted meristem).
While most of the other plants like Limnophila, Ludwigia, Undulutus, Bacopa Glossos and even Tonina and Syngonanthus are all fine and no signs of stunting. Few other plants are even showing red coloration like Ludwigia Glandulosa.
How can i get rid of these tiny leaves and stunted tops ?
Is it something related to GH? because i use almost EI dosing regime so i expect it shouldn't be NPK and micro deficiency..
Is it necessary to add Potassium while making GH mix ? I just do 1:4 Ca (4)and Mg (1) salt mix before adding to RO Water. Nilocg uses 1:3:3 Ratio while Seachem uses 1:4:8 Ratio.
Is it necessary to be K ppm higher than Calcium and Magnesium ppm ?
