I have a couple of plants that have started to flower, my question is how do you know what nutrients to add when they are at this stage and what are the percentages that I should be looking for? ex; 20-20-20, 10-20-10, 10-10-20. Well, you get what I mean!
if you are asking just the simple question of what ratio of N-P-K is for flower then you would have had a more nitrogen type for veg and a less so for flower like veg 10-5-5 flower 5-10-10 and maybe even micro or macro nutrients for the plant to thrive in addition.. consult your local hydro store every major city has em...(internet works too) the guys there will answer all your question as to how much too apply and what is best for your system whether it be hydro or soil.....
