Coco Help-Pics Inside

[Chris1]

Hey guys


Running pure Canna Coco, GH 6/9 @ 75%, no cal/mag, using tap water with ppm of 200-250

Strain is LVPK

Light on temps 70-75

Light Off 60-65

Rh=50%

Any ideas?

Ph is always 5.9-6, I feed once a day

Would have to see more pics of the rest of the plant, but if that is the only problem area it is probably light burn.

Post #2 picture #2 under Calcium deficiencies.
Looks identical.
You need to add a cal mag source, in my opinion, to coco.

what's GH 6/9 @ 75%?

 

[avant gardener]

6/9 is rezdog formula. i don't get the 75% either though.

what lights are you running?
how close to your canopy are they?

what's GH 6/9 @ 75%?

Hey krunch. GH 6/9 is General Hydroponics 6 ml/g micro 9 ml/g bloom. The "Rezipe" Or H3ad's formula or whatever

 

[Chris1]

6/9 is rezdog formula. i don't get the 75% either though.

75% of the formula...They are under a 600 right now (see pic above)

75% of the formula...They are under a 600 right now (see pic above)

so your nutrient is 4.5/6.75 instead of 6/9, am i correct?

by the look of your plant, your calmag deficient for sure.....

may want to bump up your mix. after running head's mix for a while, and getting deficiencies, i bumped it up to 10/15 and the plants have no more deficiencies and yield a shitload more then heads recipe....

 

[megayields]

Krunch - wouldnt some Silica help with the heat and Cellular wall growth and robustness? I was thinking a bit of Drip-Clean to help clean out the CoCo might be good too?

What do you think?

 

[Chris1]

I just bought a bottle of drip clean but haven't started mixing it into the res...and yes krunch, that ratio is correct

 

[Chris1]

Fed today with 6/9 and 2.5 ml/g of GH Cal/Mag. PPM was about 835, hope this clears up the issue...thanks all

i would bump up your nutrient.....

your starting with 200-250 ppm's in your water and your final ppm is 835. its not enough bro, only around 500 ppm of actual usable nutrient.....

read this whole thread....

[Chris1]

Read the thread. I'm going to take your advice and start feeding @ 10/15, thanks my man

 

[Chris1]

Here are some more pics. I watered 6/9 with 2.5ml/g Cal/mag and did the same today. I transferred into bigger pots so the coco looks dry at the top. Now LVPK is looking droopy...


From left to right, Blackberry Kush, LVPK, LVPK

This is my first try in coco so bear with me heh

It should be noted that my room temps are a bit cool, 71 with lights on. I also have a thrip issue, I ordered a bottle of monterry spinosad spray so hopefullly I can get that under control

Ok what we see here is some edges that are 'crispy' and some canoeing of some leaves as well as a waxy/shrivling/wilting sort of thing happening on some leaves.

Also, the fact that it's happening in a specific are.

It's simply too much heat, lack of moisture in the leaves. I'm having the very same thing with my 600w being too close.

What I would do, is cut off the fan leafs that have the burnt edges. The plant will try to waste its energy repairing those leaves. Overall though the plant looks fine.

Are you growing clones or seed? Just curious.

 

[Chris1]

Hey Crush. These is LVPK from clone (clone only strain I think). I'm also running Blackberry Kush from clone (4th pic)



Here are some updated pics. Temps are 79 with the second 600 installed...


Yeterday I fed at 6/10 with 3 ml/g GH Calmag. Recommended on the calmag bottle is 5 for a light feeding


Today I watered with 10/15 4ml/g calmag, ppm was 1120. PH of the solution was 5.9


The green is starting to drain in the other plants, I dont know whats going on this is my first run in coco

LVPK

This is Blackberry Kush

I sprayed today with spinosad and left them out of the tent for 3 hours before putting them back under the big lights

Any help is appreciated greatly
