Bio Vega and Bio Flores made by Bio-Canna work awesomely.
So to does Organic Grow and Organic Bloom made by B.A.C.
Half strength is plenty strong enough with any of these. Have used the products for years and can highly recommend. Being "one bottle wonders" make them super simple to use and being very concentrated means a bottle last a long time.
Add an organic P/K booster (by B.A.C.) for flowering and some supplemental amending with organic fulvic/humic/amino acids, or all 3 for best results, and your plants will love you. Add some worm castings, blood/bone meal and volcanic rock dust, and life gets even better!
Hope this helps,.........
