coco veg problems

[resinscientist]

tap water ec=.5
total ec of tap and nutes =1.4
h&g coco
maxibloom nutrients
ph 5.7-6.0

what is the age of the plant

 

[resinscientist]

month and half old lst'ed maybe 2 months now max

kinda looks like a Phosphorous Deficiency but maybe others will chime in w/their help as im not that good a diagnosing plant issues.

1.4 EC is high IME. I run around 0.8 EC max in veg rooms. If they're overfed pH in the medium will drop quickly, locking out certain elements.

Try flushing with 1.0 EC @ pH 6.0-6.1. Calibrate pH meter first if you haven't recently.

If overfeeding isn't the culprit and the issues don't go away, my second guess would be root disease. Has your water been warm (74f+?)

Hi Resin,
This reminds me of how my plants looked at one point ...
Coco too wet and too much nutes ec/ppm is my guess.
How is the wetness of the coco? I know it's hard to overwater coco, but with roots not fully developped it can easily be done and will keep roots from developping properly..
My advice: Flush with water ph'd to 5,8( or 6, doesn't really matter at this point) check ec/ppms and let the coco dry out over a couple days. While you're flushing, collect the runoff and check ec and ph, you'd be surprised how much stuff can accumulate in there after a while of heavy feeding...
You know what ppm and ph you're pouring in exactly, so whatever the runoff will be give you an idea what the situation in the root zone is...


all the best and good luck

i checked run off and ec was 2.0! and ph was 6.5!

i let the top 1-2inches of coco dry out and the rest is moist when i water.. overwatering? rootmass is massive, roots everywhere , no bugs, very white roots also..

When flushing coco its best not to use plain water, instead use a weak nute solution, .4-.5ec. Get your run off close to the input, then resume feeding. I usually feed.8-1.0 in veg and max out at1.2 in bloom. This is strain dependent, of course, but I've found that most strains thrive with lower ec feeds. Once the roots are developed and plants are healthy, try multifeeds and watch the growth explode. Good Luck

rootbound maybe?? drying up too quick because of all the roots and then locking other stuff out because of salts???

 

[watts]

what size pot is that? You may need to transplant into a bigger container at this point. It shouldn't be over watering if it has a huge root mass.

 

[resinscientist]

15 inches from light..light is enclosed 600 metal halide conversion bulb...and cooled by a 6in inline fan that exhausts out of the room .. container size 2.84L or 3qts. canopy temp with lights on 81 degrees f

pot it up

keep you pH 5.8 to 6.2 try for 5.9

and don't let them get so dry, it's not soil,

 

[watts]

Use air pots or smart pots if you want to keep plants in small containers for long periods of time.

But yeah, don't be letting them dry out in between waterings so much.

Ok with a good rootmass cancel the overwatering guess ;-)

However the numbers above point towards a too big nute concentration and that your root zone ph is off...remember if these values are in your runoff, and you poured in tap water with a rel. low ec and let's say ph of 6, it is MUCH higher in your root zone

all the best and good luck buddy
