Holes in leaves
I've started to notice that some of my plants (especially my recently purchased sunset hygro) are starting to develop some holes in their leaves. Its really mostly the hygro, but 2 of my swords have it(but not nearly as bad) The holes are little round holes, making me think its some sort of deficiency.
I know there are ferts to combat this, but i have a low tech. About 1.5 wpg, no CO2. I dose kent freshwater fertilizer and use flourish root tabs.
What do you guys think i should do here? I know that there are specific elements that i can dose, but wont these cause an imbalance in a non-co2 injected tank? Any help would be appreciated, as I really dont think I'm up for going high tech at this point. thanks.
