Nutes need tweaking ? (coco)
    #530021 - 02/23/11 07:19 PM (5 years, 9 months ago)

Which way to go tho ?, am i under or over feeding ?



See how the veins are yellowing and the tips ?

It's in canna coco, fed A and B once a day at 25ml each per 10 liters.
Comes to an EC of 1.6 and the run off comes out at 1.7.
Errrm, 20 days into flower now.

The 25ml dose is what i'm supposed to be on till the end from here in but it's obviously not quite right.

It's under a 400w mixed spectrum, 29c (84f) under the light.

Thanks for any advice, i'm leaning towards over feeding but i want a second opinion before i do anything..

Gah more problems, these things have been a pain in the arse.

I used PK-13/14 at 5ml twice and once at 10ml with reduced canna A/B (you're supposed to go 15ml for 7 days). They started going really dark so i stopped and flushed down to 1.2 EC then these spots started appearing everywhere. I've pushed it back up to 1.4 thinking it's a deficiency but it's still progressing.
PH is just under 6.





Help please, day 45 so only two weeks left.

Mg deficency? Not sure but I'd raise the ph a little to see if that helps.

The PH should be OK for coco, i've been battling PH since it was pushing up to 7 which was what was causing the curling in the first post.
It's stabilized just under 6 and i water about 5.5.

It might be a deficiency, i wasn't sure if it might be something to do with being over fed, like something coming out as it receded but i would have thought that would have stopped by now.

Do you think it could be a bud wrecker or will they hang in till the end ?

I hope so, they're doing alright besides this.



The other one's not as bad but it's more indica.
This one's a little bitch, has been right through.

I use Nutriculture PH down, about 3ml per 10ltrs. My water starts at 0.5EC before adding anything.
Humidity's around 60 usually, 50-60.

Serious seeds AK-47 is the strain.

Well when growing hydro, (from seed or multiple cuts) individual needs really show themselves. Thats the way to find hardy plants but quality and hardiness don't always go to side by side.

edit: She looks fine! Will make it fine just try and keep your ph a couple notches higher.
