Signs of plant malnutrition
In a 10 gallon tank with a CO2 and 96Watt CF light, what nutrients will need to be added, and what are signs of deficiency in nutrients in plants?
Planned plants include
-4 Leaf Clover
-Riccia (maybe someday!) :D
pale yellow leaves- then mush.
Iron is the basic mineral to add, magnesium is the new kid on the bock. Not all plants will demand rch nutrients.
CO2 is plenty for most aquatic species- of course the more you recreate its wild habitat the more it will thrive.
at present nothing- i am using raw R/O water- i am a believer of cycling the tank- starve and feed- seems to work for me.
However i use sera florena when i do fert- i use 1 cap full per 5 gallons, this contains iron and traces of magnesium. CO2 is the primary fert you should use.
I also use mineral salt- this helps open pours of the plant.
At that light level you and if you are injecting CO2 at all, you may have to dose every nutrient that there is. Plants not growing will be the first signs of NO3, (nitrogen) deficiency. Curled leaves, clear spots, brown spots, leaves falling off, and many other things can be signs of deficiencies.
I only have 33 watts of NO flourescents over my 10 gallon tanks and I have to dose KNO3 (nitrogen), KH2PO4 (phosphate), K2SO4 (potassium), MgSO4 (magnesium), CaSO4 and CSM+B (iron and other micros). If I don't dose them all I get Staghorn, BBA, string algae and some really ugly looking plants in a short period of time. And I do not inject CO2. When I did my dosing was almost double what I do now to keep up with the uptake of the plants to even have a chance to control the BBA and Staghorn algae.
Take a look HERE for more information about deficiencies and their signs.
