ok, serious head for once, think i need a bit of advice/guidance.
I was attempting to just let things grow on a bit & stop fiddling but after a couple of weeks i've started noticing a few things that are starting to worsen so action is needed.
Firstly, several things are starting to show signs of nutrient deficency, translucent leaves, small pin holes (potassium, right?) this is on old growth not the new (yet)
Some of the golden anubias leaves are developing brown edges & some brown hair algae.
Other plants, such as H.Polysperma & swords seem fine, as do the crypts (Tropica & Petchii), in fact the Tropica is putting on decent growth.
Currently running 60W of T8's for 7 hours.
My question is, i obviously need to start dosing weekly ferts.Will TPN alone be enough, considering there's no CO2 addition.What else will help? (excluding CO2)
Do i need to up the plant mass as i've been reducing it slowly over time.
Suggestions more than welcome.
