I did not want to over water them, so I have been watering from the center and moving out as they grow.
I am using Coco Coir with perlite, using Organic dry fertilizer.
I made a mix of 75% Dr Earth All Purpose 4-4-4 and 25% Dr. Earth Bud & Bloom 3-9-4 and planet the seed into the pot.
Makes sense, good to know. I will base my watering on look and feel.Yes, that's always challenging, to keep the medium wet, but not too wet (you want there to be wet/dry cycles, but even too. Not wet in the center, dry on the edges.). The problem is, the roots can spread much further than the size of the above-ground plant suggests. I've never grown in coco. But, someone who has grown in coco recently said you can't water coco too frequently.
I agree, I was originally planning on using just the 4-4-4 in the coco, but as I was reading more, some suggested the ratio.Mixing those two products that way creates a 1-1.4-1.07 NPK ratio. That's pretty low N (proportionally). I don't do that until close to mid flower.
Did you amend that into the coco, or are you mixing it in the water and pouring it in?
I was told from fellow growers, the coco with the right PH watering with help intake the nutrients better than regular soil. I could be wrong, first time with Coco.Also, coco is soilless. I wouldn't use soil nutrients in organically-inactive medium. It doesn't seem like the right pairing. I.e., if you wanted to use soil nutrients, why not use soil? (Or, if you wanted to use a soilless medium, why not use hydro nutrients... feed the roots directly, don't depend on a soil microbiology to contribute to making soil nutrients available, etc?).
It might work ok. But, it seems like it would invite problems.
I was planning todo a 50% 50% ratio in veg and do a 75% 3-9-4 25% 4-4-4 in flower. Is this too much?

So what would be your recommendation for ratio for my next top dress? (Which would be the first top dress) Another 75% 25%?50-50 would be NPK ratio 1-1.86-1.14. I don't get that high P (low N as a proportion) until late flower.
25-75 would be 1-2.38-1.23.
You are 100% right, I need to remember what made me do a Coco run with dry nutes. I will get back to you on it haha.I'm not familiar with those Dr. Earth nutrients. But, typically soil nutrients depend on a thriving soil microbiology to contribute to breaking them down, making them available. Coco by itself wouldn't seem like a great host for that kind of activity.

Should I do anything to help the nutes out then?
Makes sense, thank you for all of your help! This is probably going to save me! @az2000 (Am I supposed to be tagging you every time?)If it were me, I'd start feeding hydro nutes, treat it as soilless. Gen. Hydro 3-part Flora series? I've never grown in coco. I can't tell you what to do.
If I continued feeding soil nutrients (top-dressing Dr. Earth), I'd do the 4-4-4 by itself. Keep things simple. Cannabis grows fine with a 1-1-1 ratio all the way through. There's no need to customize the NPK ratio (given the problem you're having, and potential mismatch between nutrient and medium?).

Here is what organic fertilizer does to coco. And no this isn’t septoria...it’s advanced nutrient lock / cal mag def among other most likely.If you reply to a post (quoting, the way I am) it will notify that person (as this post should notify you).
Hopefully someone experienced with coco can guide you. I don't know if the soil nutrients already amended into your coco will be a problem if you start using hydro nutrients (GH 3-part, for example).
Good to know! Also good to learn from what others did.Here is what organic fertilizer does to coco. And no this isn’t septoria...it’s advanced nutrient lock / cal mag def among other most likely.

Ends up locking out the plant because the ph goes through the floor. It got resolved by flushing with RO water, light hydro nutes (250-300ppm) and about 150ppm cal-mag. Ph around 6.4 ppm total around 450. Brought coco ph from 4.8 to 5.7 over night.
The root zone WILL recover with a light nutrient flush.
I found my coco ended up unbuffered using organic nutes and very sporadic cal mag use. I didn’t know better so I lesson learned.
Are you measuring ph in the coco or nutes before feeding? Are you measuring the ppm/ec of the solution to know what is being fed?
You can get in-expensive hydro a&b which has calcium in it and use that all the way thru bloom.Good to know! Also good to learn from what others did.
I am measuring my PH in the water, I am not using bottled nutes, so the measuring is only the water. I am also measuring the PH in the medium.
I am not measuring the ppm, I was looking into doing this, just was on a budget.
