Some people will swear on their method. Now I'm no expert but I've been on here almost a year, have read a ton on here and have also read four books about growing this silly little, or not, weed. Look at your plants, see them and listen to what they are telling you. I do not stick to any regiment other than my waterings and they are rarely the same amount of water all the time. I also use a moisture meter, they're cheap, under ten bucks, but in my humble opinion essential if you grow in soil which I do. I use fox farms ocean forest, their happy frog and in this last grow also mixed in some scott's premium for container plants. Instead of perlite, which blows all over my yard, I dump my used soil in my yard, I mixed hydroton into my soil this time around. I personally feel that ocean forest already has a ton of perlite, while others say add more. Not only that but it seems to me water just pours through ocean forest. My room stays around seventy four to seventy seven with lights on and the humidity is under fifty percent and even goes as low as low forties. That means the plants transpire a great deal, meaning they use a lot of water. I want my soil to retain the water a bit longer than ocean forest alone allows, especially with added perlite. My plants go from very moist to almost bone dry in one day, maybe a day and a half tops. I try to do my watering in the morning when the lights first come on which allows the plant to use that water in the course of lights on. Your plants will use different amounts of water during their lives. One of my girls does not like the same amount of ferts, also fox farms, that the others seem to enjoy. Basically with a few grows experience you will be able to see and hear what your plants are telling you. I have used much less as far as nutes this grow and it's been my best so far. I too use grandma's unsulphured molasses. That's my two cents worth.
