zayackylepga Posted January 30, 2022 Share Posted January 30, 2022 Trying to come up with a fertilizer regiment after some of the plants really slowed growth. Some of the stem plants are browning at the base. Have one led bar come on at about 1pm on low then turn the other on high at 3pm and they run about 9 hours total. Co2 comes on at about 2pm and shuts off at 9pm, an hour before the lights go off. Tested nitrates-low, about 10ppm. Tested Phosphorus, almost 0. Ammonia and Nitrites 0. Wondering how much fertilizer to put in for a 15 gallon with this many plants. I dose with Easy Green, Easy Iron, Seachem Potassium and Phosphorus. Curious if anyone can direct me as to potential dosing quantities. Should I dose more than the 15 gallon amount with all the plants? Thanks for any help!!
