No you don't flush every feed... you feed everytime with runoff. That will flush some of the old nutes out with it. But you always water with nutrients in coco if using synthetic nutrients. Organic is a different ball game.

Oh, I was sure you told me to flush before each feed. Well it's great that I don't because that was a pain.

I tried the coco for cannabis style of multiple fertigation events per day (2-3). I found I was overwatering and the pots were heavy.

Again, several variables, but the best advice I got was wait till the pots are light before you feed again.

I tried that way to and my pots were heavy and definitely stunted growth. Added at least a week to my veg time. Yields were pretty good, but I was stressing the whole time. I'd love to read some hard facts on watering coco. Help lol. Please!

How big of pots and how much perlite?

Environmental factors also need to be in a good place. Especially temps.

Just thought I'd share this in here, I've been getting crazy high ec runoff levels so then I have to flush loads to bring the ec levels down, but then on the next feed the ec shot up again even though the coco was still moist. I ended up buying a bluelab pulse and testing the coco ec which reads lower than what I'm feeding (this is 1 hour after a feed) I know it's calibrated right because the solution ec is read right from it. I'm not sure if the fabric pots are catching salts in the bottom like a filter and this is giving the high ec runoff but I'll be ignoring runoff from now on, its been driving me crazy chashing these ec levels...

(Input was 1.7ec at 6pm)

I am glad you posted this. I have been looking for a solution for testing without trying to catch runoff. I will look into the Bluelab device some more, its the first I heard of it. Also glad this thread came up as I was just beginning to try and create a new schedule for the flower room. The veg room is easy, I just run an event every 8 hours. My plan was to run an event 30 minutes before lights on, another full event at 6 hours and then a final one about 45 minutes before lights out but not a full event.

I should add that these are in 2 gallon fabric pots.

I can get away with once every 2 days with no ill effects in 5 gal deep square pots atm..i have done this 3-4 occasions in flower ive done this when weather has been cooler.my pots stay over 80-85% after 1 day.1 just barely makes it to 2 days with another starting to drink more as they start week 4 .runoff ppm is within 100-150 under whats going in..but im being wasteful and have over 40% runoff which is why im keeping it in check..i reckon i could top up 2hrs before lights off and that would get them through but im in beddy byes at that time 😀 it comes down to your climate but def can water frequently in smaller pots what Aqua has taught me..im all for that.im using 60/40 coco perlite mix..

Definitely pots size, drainage and temperature are huge factors... thats why instead of going with arbitrary numbers its better to use a set feed amount and go by the runoff volume. Definitely can tweak to fit your own circumstances and grow. But doing it this way should eliminate a shit ton of issues many nee in mid late over while doing coco. Again its a guide not a rule and is best used as a concept to understand how coco should not be treated like soil for best results... by no means can you not treat it like soil but your going to be more likely to have issues and won't see the full growth benefits of coco.

Really important on the temps with this method... any any tbh. I really can't say enough the difference it makes with root temps in the increase to the speed of growth. I noticed this in my hydro going from 68 to 72-74f it may not sound like much but it really makes a difference. My coco is about 78f and they suck it up. Granted this grow is a fuxkin mess.

wow thats a hot rootball. Dyna gro warns not to keep their nutrient solution over 75 degrees f.

Awesome thread with an awful lot of informative material.

I still have a couple of questions.
From what I’ve read, this advice is for those who are growing is straight Coco Coir.

is it the same for those of us who are growing in an Amended Coco Mix?
For example, the Coots recipe with Coco as the base media, instead of Peat?
