Hi all, my tanks 14-8-8 inch, lighting is 27W T5PC, CO2 is light green using 4dKKH in the drop checker, sera substrate, and im using the All In One fertiliser from the link on this website dosing at 4ml daily with 50% water change at least once a week, lighting is on 10 hours, phosphate from the tap is 2.5 with a PH of 7. The background plants in my tank are slightly out of shape and think its a calcium deficiency, the only plants that dont seem effected is my glosso. The tap water has a GH of 60ppm and a KH of 20-30ppm but the tank has a GH of 140ppm and a KH of under 10ppm so what is going on, going by pics of deficiencies i would say this is deffo calcium or boron but since ive changed to the all in one fertilizer its not got any better so suspect its got to be calcium. All help greatly appreciated.
