I'm finding that these pot plants can handle a ton of nutes. I have been watering mine with almost double of 10/30/20 with a tablspoon of molasses for a mo now. The girls are soaking it up, just today i notice a few lower leaves browning, but no biggie. One of my girls is/has been drinking twice as much and very little burn, the buds are fattening up nice. I'm thinkin the more the merrier, and as soon as possible, workin them up.
Also the 12/12 for flower is wacked, more light equalls more photosynthsis, equalls more growth, I had super skinny buds until i upped the nutes and light to 16/8. Oh, the light is a 400w MH, with T12 florescents, fatties on the way finally.
