Dosing: 6 mL Flourish potassium, 10 mL Flourish

Notes:
I was worried about the small holes in the older stargrass leaves, so I dosed 6 ppm Flourish potassium to see if there was some potassium deficiency. I had added Equilibrium last night but forgot about it today, and since Equilibrium already has potassium, so I didn’t need to add the dose. Won’t do that again. Nitrites have increased, probably because of new batch of fish (4 otos, 2 SAE, 1 black molly) added from the weekend. Some of the old leaves in the Rotala rotundifolia are yellow in parts. It might be a potassium deficiency, or possible nitrogen deficiency.
