Need Nutrient Help

I planted a few clones into 3 gallon pots with fox farm ocean soil a week ago. I added some clay pellets because it's very dry here. I also bought a cheap bottle of Botanicares CNS17 bloom 2-2-3. I was wondering if anyone had any experience with this brand. It says to feed the plants every watering(I thought this was strange). And from what the directions are saying you can use this for pretty much it's entire life in all the main stages . I have fed them twice because I've only had to water twice (1 tbsp per gallon which feeds all 3). They seem to be fine. Im just trying to avoid turning them into hermies. I'm clueless on this subject, so if I have to start all over I will understand. I added pictures of the instructions and the bottle. I just found it to be weird compared to nutes I've used in the past.

Three gallon is a small pot make sure the soil doesn't get to hot .The FFOF soil should have plenty of nutes for three to four weeks.That stuff is for flowering i would use some with a higher nitrogen content in three or four weeks up in till the first few weeks of flowering then use your CNS17 to finish flowering.Good luck and visually let your plants tell you when you need some nutes and apply as needed.
