well just a quick sum up is, when a plant is in veg cycle, They intend on needing more Nitrogen(n), It helps with the growth of a plant. Not so much Phos. (p) but still use some because its good for the roots. Phos.(p) Is used more during the flowering. So more (p) and less (n) but still use nitrogen also. Example: use something like 10-5-7 for veg. For flower use something like 15-55-11 bloom booster. Thats what i use.(Not saying you have too)Plants want more (p) thats what produces bud. You will see those numbers on all plant soil and nutrient products. The first number is the amount of Nitrogen(n), 2nd number is the amount of phosphorus(p) and the 3rd is potash(k). Just remember to not over feed with nutrients,(I use it every other feeding, once again not sayin you have to, its something I do)Every grow is different and amazing. just have fun with it, experiment, its an ART!!! lol Hope this helped you a little.
