Gorilla zkittles

We are in week 5 since start of 12/12. I am trying house and garden for the first time so may take a bit of getting used to. Any advice or suggestions to get the best or any reviews about house and garden would be appreciated. I'm using the roots excellurator, bud XL, top booster and top shooter. Ending week five and she looks great. After today I will stop the house and garden top booster and start with top shooter. From now on I will cut the calmag out and possibly the emerald harvest grow too. House and garden advise that to add your base nutrients and get the mix to 1.2 EC before adding the top shooter. I am still learning the right time to administer or cease the different nutrients.
