Just started flower how am I doing?

Yaaay! I just threw my 3 baby's into flower on sunday. Their 1 month old pretty much to the day. On the right is the GG#4, left is superglue, and bottom is master kush. Aka the bush. Ive got them under a 400 watt hps, with FFOE and their trio of nutes. I hit them with open sesame last week with a PH of 6.0, And again today. I just wanted to know how everything looks.. I didn't top or anything. Just letting it grow natural. Their about 1 foot - 1 1/2 foot tall. And smelling pretty nicely thanks for reading let me know what you think!

Wow, you flower pretty early... looks good for 2 weeks into flower I guess. You tried a micro grow? Or you just prefer to flower fast and don't really care for yield ?
