Coco first time

Www.imgur.com/a/Va0l3D5
3gal canna coco
An mgb nutes
Runoff ph 5.3-5.4
Was feeding with blumat at about 600ppm +200 tap ppm =800ppm
Any guesses ? Is it nute lock out? What should i do?
Btw flashed yesterday

Mr Magu
Dr. MJ Coco is a genius, go and listen to his podcasts; it is likely its cal mag if the coco was not buffered.

good luck

what the issue i just cant see what the stress is all about if u are talking about the mild leaf burn well jesus that is not a issue lol back of the ml rate if not keep going she will push thru that just keep it at 800 or so for the next week or 2

runoff is a bit too acidic for coco .. salt accumulations bring the ph of the medium down
i would be curious to know the ph of you feed.. i would feed at 5.8 in veg .. and look for a runoff ph of 6.0-6.1 if plants eat normally

do you give enough runoff too ? around 25% of the water used every day must go down the drain .. if less i experimented salt accumulations .. even feeding around 1.2-1.3 ms

You burnt your plants, you then backed off the nutes and now you need to add some nutes again, other wise they will go yellow.

wondering if mg is not locked .. how much ppm is your runoff ?

You look short on Mg...nothing else. I don't know your nutrient line, but be sure it's complete, and keep in mind if you're growing in coco, you'll most likely need to supplement more Mg and Ca than one might in other mediums. Epson salt, in this instance is your friend. Good luck.

Ah, and if you are supplementing Mg, check your pH going in...if it's as low as your runoff, you're locking Mg out. Good luck.

I grow in coco using blumats and have for years. I never check runoff for pH or ppm. I focus on what goes in. If that is on point then everything else falls into place. That canna coco is pre-buffered and for that matter an decent coco is rinsed and pre-buffered. This isn't years ago when they would just scoop up coco husks from off the beach and bale it up salt, gum wrappers, and anything else that ended up in the pile. It's rinsed multiple times and buffered. I'm not familiar with MGB nutes. I just use calcium nitrate, a micronutrient blend, mkp, magnesium sulfate, and potassium sulfate a couple times in flower. I have never used calmag in my life and I never have any issues. Flushing is not your friend in coco if you're flushing with plain water. Always use at least a weak nutrient solution when watering in coco and pH what's going in.

I now see the original post was September 22nd.

I was mostly concerned about yellowing, now i have more small plants and they do the same thing... they aint stunted tho, so i think its ok. I ll try to add more calMag. Thanks for replys.
What about feeding multiple times a day with pump and bubbler in it ? Lets say 200ppm tap and 300ppm base nutes 2 times a day? No runoff, but using drip clean. Would it work ?

feeding multiple times a day would be beneficial, its what i do and the plants grow faster and stronger

you need to charge your coco before you use it. coco comes with a "deficit" , it has a lot of open receptor sites that will bond with magnesium. if you're buying loose coco, add at least 100 ppm calmag to each watering all the way through veg. if you're buying blocks and rehydrating it, rehydrate with 350-400 ppm calmag to begin with. that will fill most of the empty receptor sites and you won't have nearly as much problems with mag

I ll give it a shot next cycle if i ll find solution now as i kinda want to abandon coco otherwise. Thanks for your reply

I read that people dont even put calmag until 12/12
Heres latest pics. I have more problems. Bottom leaves on new ones doing same stuff as bigger one was doin. But bigger one seems to be okay now. I hand water bigger one about once every 2 days tho
Theses puppys get water twice a day now in small amount...(i have bubbler in reservoir tap 200 ppm, 350 with calmag and 650ppm/ 1.2ec with nutes total)
I was thinking that its chlorosis but then i talked with my friend who have some plants next door and he doesnt put any calmag in his coco, Plants look very healthy and all.
Im confused. I think i ll water them every 2-3 days now so they can get bigger roots and all.
Any ideas now?
I dont think its calmag. Overwatering maybe? No? Wtf then? :S

i read it before. but as its uses different nutes brand, it doesnt fully help me. I understand that i can hold coco wet all the time and i do runoff, use proper good ec n stuff. its just weird, why am i getting yellowing and brownish tips. im already giving about 0.4ec calmag agent
does anyone have pics of underfeeding coco ?

I learned a lot growing in clear solos. Root development is key.

Rootbound = ready for multi-feeds.

Before then, wet/dry cycles to dev roots.




After xplant into 2 or 3 gal fabric.....must again allow wet/dry cycles. Mutli-feed too soon - not good.

Way overdue for xplant.... Lol

that could be my problem. thanks . will do smaller pots next grow. i think 5gal is way to big for my needs, and they are definitely not rooted well enough for multi feeding right now.
that would explain why bigger plant in 3gal fabric pot, which is fully rooted is growing fine. and im doing everything the same for that one as with smaller ones. THANK YOU

But just know....I've effed up with 2gal and 3gal - a combination of impatience and ignorance - trying to water too much too soon. Only slowed growth, and caused nute build-up. ended up being a chitty run, etc...
Experiment on a few extra plants if possible to compare differences in methods.

What about h&g drip clean? Do you use it?
Can i do no runoff with it ?
