Adding .5ml to 2.5g and 3ml to 26g of Kent Freshwater Plant nutrient a week. Plants in 2.5g and 15g are doing really well, but the ones in the 26g just seem to be slowly wasting away. I’m not sure what the reason might be. Actually, I’m going to add 15ml of of Kent Freshwater Plant to the 26g this week and see what happens. What’s really strange is why the Brazilian Pennywort is doing well in the 15g at home but not in the 26g. I theorize the constant addition of RO water for makeup water left a some type of mineral deficiency in the water.
