Re: Holes In plants

Your alkalinity is 140 German degrees? Please tell me that was supposed to be ppm or there was a decimal in there somewhere. That's a lot of baking soda. Your tank must keep your whole house smelling fresh, not to mention the lovely white substrate it must have.

Re: Holes In plants

Well it's hard to say, but in general holes in leaves mean potassium deficiency. Is that 20ppm No3 from Potassium Nitrate? Also the light color growth may be from lack of Iron/ traces. Looking at your levels I would also recommend to bump up the phosphate to at least 1ppm, but 2ppm wouldn't be bad either. Another thing you can do for your swords is put some Flourish Tabs under them to give them an extra shot of Iron.
