fast buds grow

hey fellas, I'm new here and I am currently running some fast buds strains. the gorrilla glue, tangiematic and stardawg. I'm doing 3 gg, 3 sd and 1 tmatic. all of them got a touch of tacoing but none as bad as the stardawg. I use two appollo 600w my veg, hps flower. my lights are about 41" away...
