My thoughts are<If you are using FFOF soil in a 5 gallon bucket you should start nutes at 1/4 strenght on the first watering , if you transplant correct and drench the soil it will take a Min of 1 week to need water , then the next water go 1/2 power I drench everytime I Feed/water and it takes 7 -8 days to need any water some times longer so I feel by the time thay are 6 weeks old you may have only watered/fed 3-4 times then i would start full nutes ,every other watering , just keep an eye on your plants they will tell you whats up , check your PH maintain at 6.5 Happy Farming ,Cajun
