Have plants in 5 and 7 gallon containers and have become fairly large. Some are 5’ but most are 3.5’ to 4’. The larger ones will drink a gallon of water a day basically fairly easily not including what may run off from drainage holes. My question is FF nutes say to feed about every other watering which would result in 3 to 4 times a week for me. I’m only feeding about half strength at 1.5tsp per gallon of water per plant weekly but should I be upping this or feeding every other watering as I feel I’m just flushing the nutes with plants needing so much water. Any advice guys/gals on your thoughts? Thanks!

Check your run off ppm then get your ppm to 1000 and keep it there. Feed accordingly from there.

According to foxfarm schedule you should only feed 2 times a week
I have to use 2.5 gallons of water a day my plants are in 10 gallon pots. I use dry amendments only suppose to feed once in veg and twice in bloom but the rain keeps flooding plants and washing nutes awsy

Feeding schedules are sometimes irrelevant. All plants and environments are different, necessitating different levels of feeding per grow. Even given the same environment, plants can demand more (or less) nutrient doses. The last plant I grew required double doses of nutes. Most other grows I’ve done have not.
To be clear - feed as necessary to maintain a runoff PPM of ~1,000. Feeding schedules are only estimates that may or may not achieve the proper runoff PPM.
Plants aren’t that different than people. Some people are going to be overweight at 1,800 calories per day and others will be underweight given the same daily caloric intake.

This was a big mental block for me. I would read about different feeding schedules and amounts per feed. Then i would read about PPM needing to be at 1000 - 1500 during veg or flower. I was having problems wrapping my head around this. I am now starting to clear up this mental block and understanding that these companies want you to use up their products so you buy more with complete disregards to my plants. So now i am learning to adjust my PPM before i pour it into the medium after checking the runoff amount.
So say if i have a PPM of 400 in the run off and it needs to be 1000? I adjust the PPM going in at 600. This brings it up to about 1000 and the plant is happy. I dont pay any attention to what the instructions say. I just pay attention to the runoff PPM and feed as required to keep it at 1000 at all times.

This is exactly why I rant about “bloom boosters.”

I’ve been following you and i am learning a ton! Remember, i was the guy killing my tomato plants with Miracle-Gro until i joined ILGM… Now, my plants are thriving and far away from being burnt up and left for dead…Thank you!
