Alfalfa pellet, cheap cattle feed (horses normally) and you need nothing else other than this in veg. 1 hand full in water after a day it turns brown, dilute that again and use.. Magic stuff. Triacontanol in there too.
Spiralina like ultraviolet said is, also chlorella, Chlorella is a nutrient-rich microalgae used in agriculture as a natural biofertilizer and biostimulant, promoting better plant growth, stronger roots, increased photosynthesis, and enhanced disease resistance by supplying amino acids, vitamins, hormones (auxins, cytokinins), and minerals like iron, phosphorus, and potassium. Provides essential macro- and micronutrients (N, P, K, Ca, Mg, Fe, Zn) and organic substances that improve soil health and nutrient uptake.
Hope this helps mate..
