Are you having any problems now?
Let's start at 1/3 of EI. We have to start somewhere and take it from there. Everyone's aquarium is different and requires its own tweaking.
1/4 tsp KNO3 3X weekly
1/16 tsp KH2PO4 3X weekly
5 mL Flourish 3X weekly on opposite days of your macros.
20% weekly water changes
Do you have hard or soft water? If it is soft, you may want to get some GH Booster or Seachem's Equilibrium. 1/4 to 1/2 tsp 1X weekly after water change
I took the following dosing regimenn and used 1/3 of it.
50% H20 change-weekly
3/4 Tsp-KN03 3x a week
3/16 Tsp-KH2P04 3x a week
1 Tsp-GH booster once a week
15ml 3/16Tsp-Trace 3x a week
4-8ml-Fe/Iron 3x a week
- If this works out to be too rich, dose 2X per week.
- If it is too lean, add more.
- Watch for holes in older leaves. This indicates a potassium deficiency. You can dose K2SO4 or KCl (no salt from the grocery) if this happens. Usually dosing at the same amount and rate as KH2PO4 is sufficient.
- Try it for ~ 3 weeks before you make any changes.
Let me know how this works out for you.
