The Subject says it all i was wondering because i have grown a many a times but never used ferts and am thinkin about doin it so i was just wondering...
dependes how rich ur soil is. not untill ur plant has a good root system tho. i like to water in the morning and feed them every third watering nomatter wot day of the week that is. this water on saterday thing i think is bad. that way a plant gets to much as a small plant and not enough as a large plant. by judgein feedin by watering ur letting the plant tell u wot it wants.
