I increase feed when my plants need it. I’m pretty reactive when growing, regardless of medium or nutrition regiment.
Wasnt always this way I used to feed based on schedules or instructions on the package.
I dont think increasing food input beyond what a plant needs is going to realistically increase yield. Just as long as they’re getting enough of what they need.
Way I see it, all plants have different needs and no matter how hard we try to meet those needs we will never be perfect, and even if we do get it perfect, what works for one plant perfectly might not for the other.
So my strategy has just been to push it until I see issues then back it off and hold it there. That way at least I know they’re getting enough of most things, even if they may still need others. I’ve yet to straight up kill a plant and some of my biggest plants were ones that were pushed “too far”.
