big question about nutes.

So I've been following the feed schedule that came with Fox Farm Trio. I mix the recommended amount, however I don't know whether to feed 1 cup or the full gallon. Do any of you guys have suggestions on this?

Next, the trio is all I'm feeding. I'm week 4 into flowering. Is there any other nutrients I need to be giving my plants?

Please don't take offense. There is a WEALTH of great information in this community. I am guessing the reason for lack of response is the nature of your questions point to the obvious of not reading and/or finding this easy to obtain information for yourself.

Feed your plants as much as they tell you. Depends on your lighting, medium, ventilation, strains...etc.

Fox farm soluables are great too.

Best of luck.

Once you mix it up, water until you get a decent amount of runoff. That is how much she needs so far as volume of water.
