hmmm, i dont really use nutes for vegg. as they usually cause more problems than they are worth, but when im flowering, (someones gonna give me shit for this) i use Miracle grow, the blue water soluble stuff, i use a weak strength solution in rain water (for extra minerals) and feed with every watering, as the MG i got is pretty high in phospherous, and its slow release, i can give it a lot of weak feeds and then just run clean water through once a week, i havent had nute burn yet but the leaves are very dark green, i know alot of ppl say not to use miracle grow but if you use it right, its better than nothing, my friend got a couple very healthy 2ft plants using MG, but a heatwave dried them crisp in about 2 hours....crazy...
