Confusion about Fox Farm Trio while using Coco Coir and Perlite mixture

This is my first time growing and I need to know how to use the nutes. I need to know how much to give and how often. I looked at the schedule but I am confused about how often and the amounts I should give. After some reading someone said that I should use significantly less than what FF recommended. Also I don’t know if I should feed each day or 1 time per week or a different schedule. PLEASE HELP!

I would start at 1/4 strength nutes and full strength cal mag water every day to some runoff 20% +/-

Okay so it should be to 20% runoff. Thank you so much!

I have never used those nutes. But do use GH which is very similar. And start with 1/2 like @Allinherhead mentioned. I wait till I am close to 3 weeks old before I got to 1/2 with mine. I don’t know how AN is with autos. But for most I do. I stop at 1/2 strength. I do work my way up to full as I see them show they are ready for more. I personally shoot for a 3 - 4 cup run off when feeding or watering. I feed for 3 days then do a water with just cal mag added to it. If you keep notes of what your run off is. It will help as a guide for what to feed. It also will help you to know how much you need to feed each day. This is what I made to keep track of my plants. I am in coco as well

How much water do I give at a time?

It doesn’t have to be exact just water slowly, (I use a solo cup on the stuff I hand water) until it starts coming out the bottom of the bags. The amount that takes will be more as the plant grows. Mine are using 25 gallons a day. The idea of the runoff in coco is to make sure the roots get saturated and the old gets flushed out.

Thanks Allinherhead!! Wow 25 gallons is crazy. Can you give me an example for what I might feed a seedling?

Are you in soil or coco, sorry if you already said. I fell down the stairs and at the least have cracked some ribs so dealing with the pain having a little trouble keeping these threads straight.

Sooooooo sorry to hear about your fall. Hope you feel better really soon!!! I am using Coco and Perlite.

I use a 150ml syringe to water seedlings. Purple kush in coco 17 days from sprout.
Transplant day.


They were put in 1 gallon transplanters. I gave them 300ml each.
2 days later they received 500 ml. Enough to have good run off.
As they grew the water/feed became every day rather than 2-3 days. Always gave enough to have good runoff. 600 - 750ml until moved to 5 gallon fabric pots.

For comparison, when they were in trays they were only getting 10ml or less. (20 or 30ml syringe)

Thanks!!! That helps a lot!

It was my understanding that you feed every day when using Coco and Perlite mixture… Am I correct in my understanding?

I would qualify that to say every time they need water. Depending on the plant’s size, the size and type of the pot, you may go more than a day. The concept is called fertigation frequency. If you are using coco I highly recommend cocoforcannabis. They cover all thing coco including feeding.
