I've been alternating aquarium co-op easy green and flourish, about once every 3 days. Plants have been growing very well and the total plant Mass has more than doubled in the past 2 weeks (it is a new tank though so doubling is much easier to do thAn if it were already heavily planted).
Anyway, I've noticed my phosphates are always below 0.25, and more often than not they're actually 0.
Should I consider more frequent fertilization? Or should I consider adding only phosphorus? From what I've been reading, it seems like it's optimal to keep phosphates up somewhere between 0.5 and 2ppm depending on who you're reading.
Or should I just not change a thing since everything seems to be growing so well? I'm leaning towards this idea... But I just wanted to make sure I'm not gonna run into some major issues down the road due to long term low phosphate
