Compost + chemical fertilizer while flowering.


New Member
Hello. I was wondering if I could use both compost and chemical fertilizer at the same time. I grow white widow, 1 week into flowering. For more info about my growth check my signature,please. I allready have compost in my soil mix and I would like to add some chemical fertilizers. I have one fertilizers with npk 4:6:6, I'm thinking to use it for next 2-3 weeks and then I would use 13:40:13 from then, sometimes maybe switch to 4:6:6 because I think 40phosphatus is kinda too high. What do you think?
