You question is vague for an exact answer, there are a few variables.

General rule of thumb
Dry Dosing mAcro's.
Trace and Fe 1Tbsp per 250ml or premixed retail product's.
1/4Tsp KN03 per 20gal
1/16Tsp KH2P04 per 20g
5ml Trace per 20g
1-2ml Fe
all the above 3x a week

Assuming/depending on wheather you have good light, C02, and a good plant mass, once light intensity reach's a certain point, more plant's & nutrient's are required...

Light intensity should be governed for best result's

Take a gander thru Rex's guide for more NFO
