Always start with 1/4 strength nutes all the time. Set up a schedule. I water when needed by the weight of the pot so I never over water. But do something like every other water use nutes. Start a 1/4 on day one, wait 2-4 days to water, water using water, then got half, stay at half for a week and see if you get any tips burning. If they are still looking good, keep going at 50% or go to 75%. You should flush once a month when using nutes and remember you need to do a nice flush 2 weeks prior to eta of crop and dont water the last week. This will make the plant pull all nutrients from itself and the leaves. It will yellow like crazy but ur budds will not taste chemically. Iv also read that you can leave the lights off the last 3-4 days will imporve dry time and swell.

BTW-you might wanna even start at 50% and try adding the bloom nutes right before you turn the lights over to 12/12. The NPK is low but youll have to give it a try to know.
