Can't seem to get coco growing down

[Bobbo4200]

Hello,
I have been growing in coco for almost a year now, I have had some luck with some plants-and others not so great of luck. I seem to always be running into Nitrogen Toxicity... I am not going to feed as heavy, and also incorporate an every other week flush with pH'd water into my regimen. I will use Clearex sometimes during the flush, but not every flush. Any tips, or suggestions for coco? Thank you for the help.

Do you use an e.c meter mate? If not there is a great start You can control the nutrients better than the back of the bottles recommend. I use 1.3 ec for young rooted clones increasing to 1.8 in late veg and have hit 2.2 in flower withe no adverse effects. Good luck.

dank demon has good advice. a proper electronic EC meter is crucial to knowing exactly what you're feeding your plants. $70 is nothing in the grand scheme of this hobby.

i play it safe and run 1.2 ec for rooted cuttings up to small plants and hit a max of 1.6 ec in flower. I dont adhere to the philosophy that more nutrients = bigger yields.

This!

Most of the time I don't go over 1.4 in flower. Maybe with PK boost I'll hit 1.6 but then it's right back down to 1.4

Also I would not recommend plain water flush, instead flush with mild nute solution. If I ever flush I do so with 1.0 until runoff is 1.0

Thank you all for the help, I will look into a meter

Which nutes are you using?

I wanted to chime in and say that I concur with this advice. Even with my tap water coming in around 0.45ec I still won't break 1.6ec with nutrients added. Typically I am somewhere between 1.2ec and 1.4ec through the majority of the grow.

I prefer not to flush with plain water due to the media's affinity for some elements more than others. A method I have had good success with when it comes to overfeeding as a habit is running 1/2 strength nutrient solution between your full strength feedings. Alternating like this will help you maintain your nutrient ratios while still removing excess buildup.

Nitrogen Toxicity is sometimes associated with "Eagle Claw." This can be misleading as Epinasty (or low O2 levels at the root zone) display in much the same way. I would show equal concern to the state of your root zone (water cycle, water temperature, root zone supplements) as I would to my nutrient profiles being off.

Thanks guys! I am using Flairform's GreenDream Grow and Bloom, and also was using Rock Resinator as a bud boost in flower. They are coco, hydro, and soil nutes.
I am going to go a little easier on the nutes from now on for sure

I almost never go over 1 ec these days, my tap is about 0.1 though. Would try a 2 part dedicated coco nute like canna, makes it easier to lower the N towards the end of the grow.

Go with what snowcrash says.
Skip the clearex at least until the end.
Ive played with florakleen and I will say that it pulled a shitload of salts out of my pots that 1/2 feedings wont do. It literally turned the bottom of the pots white from built up salts.
I just dont see why anyone needs to do that. I prefer to slowly lower my nutrient levels at the end.
I wouldnt ever use something like that in the middle of a cycle. You will destroy the buffer in the coco and shock your roots.

Ok, thank you

I have had great success with coco. I always add great white and azos directly to my coco before I transplant my clones. I early veg at ec: 1-1.2. I allow my coco to get 50-60% dry before I feed. This usually is every 2 days in early veg (1 gallon pots) to every other day through out flower in 10 gallon pots at ec: 2.0-2.1. I begin flush with filtered water week 7-8.

I really don't see how you can grow with Coco without a ec or ph meter

 

[GreeeeN GRassss]

if you know your set up and the EC of your water its not that difficult to grow without an EC meter of course depending on your system and how many plants your growing, i am hand watering a small amount of plants. my EC meter broke and i didnt have one for 1 year until i moved and i needed to get one because the water in the new place was terrible. now im using rain water and my EC meter is essentail,

growing without an EC meter start off your feeds low build up slowly and have a nice amount of run off. watch for usual signs of over feeding then back off on the nutes.

PH meters are the most important part of my grow. its like a diabetic not checking there blood sugar bad things will happen.

 

[Bobbo4200]

Thanks guys, what are some good but fairly inexpensive eC meters? I have a Tri meter by Nutradip, it does pH, temp, and ppm's. I only use the pH part though. I will have to look up the conversion of eC to ppm's.
When I feed, I feed til a good amount of runoff-and it is usually soaked up by the next day so I repeat the feed. Is that not a good idea? Should I do that, then let em' dry out for a day-doing a feed every other day? Thanks again

I would recommend bluelab Truncheon for cheapish reliable ec monitor. I used to use a wet and dry cycle with great success, but I now use a nutrimatic drip timer so cannot run a wet/dry cycle but I still acheive great results using 30% run off. I have notoiced no visilbe differences between overall vigor and bud size weight or taste.

 

[GreeeeN GRassss]

ye blue lab truncheons are very good, i have mine a few months now and still working fine, i use wet dry cycles to build root mass then i water every day.

 

[Lesterburnum]

use coco specific nutes and ph water in. Period. hahah.
Good luck bro. You will get it.

 

[RedBeardy5]

Blue lab meters are defiantly worth the cash, also more reliable in my experience.

Spot On !!!! every word !

I've been using Oakton meters for about 2 years with very little calibration needed & i check them every sunday regardless .
