Clawing leaves - what’s wrong?

[Mrjazzcat]

So I’m Growing autoflowers in coco coir using Biobizz range of organic Nutes.
day 21 the leaves start turning down and I can’t figure out what’s wrong. I’ve moved the fan away from the plant in case of windburn, changed the Nutes to use a little less nitrogen in case she’s about to enter flower as it normally happens around day 21 on this strain. Moved the lights further away. I water at a pH of 5.8-6.5, the medium has a pH of 6. The temp stays between 21c-26c. The other 2 of the same strain are growing rapidly but this problem seems to be getting worse.pro

You Watering daily with 1/4 strength nutes

She looks dry as a bone

 

[Mrjazzcat]

Yeah man. She gets about 1l a day at the moment, always with Nutes. Ec is about 1200 at the moment.

 

[Dirk8==D~Diggler]

Flood that bitch on the daily you can’t over water it in the coco

 

[Dirk8==D~Diggler]

3 gal?

 

[Mrjazzcat]

5 gal fabric pots.

I’ll up the watering then. See if that helps. Thanks

 

[BobThe420Builder]

1l in a 5 gal.... seriously

2 gal minimum

She is suffering


Step in up!!!

Ohh shit. I normally transplant but I planted these straight into the 5 gal as they are autos.
Thanks!

Yeah you’re going to see some ugly leaves down the road if you keep letting the coco stay that dry

 

[BobThe420Builder]

That's not 1/4 strength

 

[Mrjazzcat]

That's not 1/4 strength

Nope, it’s about 3/4. They had nitrogen deficiency pretty early on when I was using 1/4 so I just upped the EC by approx 100 points per day until it was fixed.

Could the clawing be from the EC?

Yer burning them up

Better research growing in Coco

What EC would you use then?

Everything I’ve seen says 1000-1400 for early veg in coco.

 

[Jeffislovinlife]

I'd do what Bthe420B is saying to he has helped me out in his own way hope you get it straightened out

 

[BobThe420Builder]

I don't do ppm,

I go by manufacturer suggested strength

Are you confusing ec with ppm? On a 500 scale the 1400 ppm is 2.8 ec. Pretty stiff especially if your not getting runoff. easy to get buildup.

It’s definitely EC I’m using, I think the ppm is between 550-600 on my pen.

Ok so what is the EC of your fertilizer solution? Have you tried checking the EC of the runoff if there is any?

 

[Mrjazzcat]

Using an EC of 1200. I’ve just watered and check the run off. EC is 2500.... ouch!!

Just flush them through with ph’d water until the EC comes down?

 

[Merlin1147]

Wow so your meter is reading in microsiemens That’s interesting. 2.5 isn’t too bad.
