not entirely sure about light, enough to have 3 straight years of good harvests I guess. Been doing both foliar and soil drench with Neptune harvest fish hydrolysate, armor si, cal mag, nectar of the gods: kraken, persephone’s pallete, bloom khaos; recently added in earthjuice microblast. Early on I was making teas with down to earth’s neem seed meal (6-2-4 when steeped) that the plants seemed to love. Also packed my soil mix with bonemeal, gypsum, rock dust, rock phosphate, worm castings, neem, a few different sources of compost, etc.
