First Auto in Coco grow

Walk me through your feeding schedule and how much you’re watering.

did you precharge your coco and what’s the PH of your mix?
Tap or RO water?

 

I use Mother Earth coco too; it’s wonderful stuff.

Now let’s fix a few things before I ask more questions.

In veg, you want to shoot for 5.5-6 PH.
In bloom, shoot for 6.0-6.5 PH.

usually sitting around 6.0 is ideal.

Also, your plants needs water. More water than what they’d need in soil. You are basically running hydroponics and it should be treated as such.
That said, you NEED to water at least 1x a day to at least 10-20% runoff. 2x is a little better. And the older they get, the more frequent waterings, the more they’ll appreciate it.

Now, you are using distilled water. You NEED to add calcium/magnesium. I would start at 5ML per gallon to get your coco caught up, then taper down as soon as you see deficiencies clear up.

My guess is that you didn’t properly pre charge your coco and that’s created a deficiency. Just water a lot and keep your medium very moist. Things will turn around very shortly.

 

I agree with almost everything you said.
I assume when you say "water", you mean feed?
Also, Mother Earth coco is buffered and can be used right out of the bag without pre-charging........I never have to pre-charge anymore.

 

Yeah lol water is always feed for me

And I thought so too, but I had a bit of a cal/mag def when I didn’t pre charge my Mother Earth this year.

 

Glad I found this post. How much water should I be feeding a 3 gal fabric pot? I messed up at the very beginning and wasn’t using enough cal mag and probably not enough watering. One of my girls is suffering early but hopefully it all the new growth is good. So basically now at week 2-3 ive been feeding every 2-3 days with a full gallon. I will start watering daily. I use cal mag and the GH fseries. Micro /grow /bloom. I watered my sickly girl today using a full gallon with about 550 ppm and 5.8 PH. The runoff was 400 ppm and 6.4 PH. So basically is a gallon per feeding sufficient? And why is my PH higher coming out. Thanks . this is also a autoflower in mother earth coco perlite mix 70/30. Mars hydro 1k led. Any good links on what the target ppm should be throughout the life cycle? Sorry for the thread hijack I thought this was a different thread.

 

Here’s a outline for you



If you feed only once a day, I’d shoot for somewhere around these numbers above. But if you are doing multiple feeds a day, you can shoot for a little lower PPMs.
Just keep in mind this a general schedule and not strain specific , so read your plants and adjust accordingly.

 

Thank you! How about watering? Is there a rule of thumb for coco? Per gallon of medium.

 

You want to get run off to 10-20 % if you are watering just once. If you are doing multiples, you can just water to where you know it’s fully saturated. The 10-20% is to help not get a ton of salt build up. No general rule, the coco just loves to stay moist, so if you can ensure that, you’ll see killer results.

 

I grow in 3 gallon smart pots in coco
10 litres of water does 4 plants perfectly with runoff on week 6 veg
I water once a day every day

 

I can see a big difference. They're slowly coming back to health

 

Good luck with that in coco.

 

Are you using a 12/12 light schedule for the auto?
