I'm enjoying some decent growth in my tank but I've come to the point where I just want more.
It seems as though that there are two main problems:
1) small brown slit-like cuts form on the (older) leaves of many of my plants (Ech. Bleheri, Lud. Repens, Bacopa Car., Giant Hygro).
2) my Ech. Osiris and Crinim Calamistratum (slightly) have yellowing leaf edges.
The sag.,crypts. and val. are fine.
Ph=7.0; Kh=6; Gh=10; Co2=20ppm @3bps;P=1.0; N=15ppm; K=??; 2.8wpg
Mon- 50% WC; 1/2 tbs Mg2So4; 1/3 tsp K2So4; 1/4 tsp KH2Po4; 5ml Fe
Tues- 1tsp KNo3; 15ml TMG
Wed- 1/4 tsp KH2Po4; 5ml Fe
Thurs-1tsp KNo3; 1/3 K2So4; 15ml TMG
Fri- 1/4 tsp KH2Po4; 5ml Fe
Sat- 1 tsp KNo3; 15ml TMG
Sun- 1/3 tsp KS2o4
So, is it not enough Co2 (do I really have to go higher than 3bps), is light the limiting factor or are my ferts unbalanced???
Any suggestions are welcome
