Am I feeding my girls too much?

Hi all,
I am referring to the amount of NPK and micro nutes as opposed to over watering. Currently I am in the flowering phase at differing interval on my 4 plants. I am using MG 15-30-15 bloom booster in addition to AN Big Bud and Bud Candy. One of my plants is about to receive AN Overdrive in lieu of the Big Bud since she is coming to the end of her life cycle.
My general feeding is every Friday (if it hasn't rained in the last 3 days):
1gal per plant

5gal bucket containing:
4gal of water
4Tbl of MG 15-30-15
20ml of Big Bud
20ml of Bud Candy

6.5pH soil and water

Is this too much?

No IMO thats not to much, Only thing I'm wondering is how large are the pots that your girls are growing in. I'm growing in a 10gal pot and I water depending on the heat every 3 days and I'm using 4gal of water on her. And I am also using advanced nutrients with Sensi bloom base. I guessing my plant has about 3 weeks left maybe less.

My girls are in the ground. I have a hydrometer in the ground about 8" from the base of each one. So, generally I feed about every Friday.
