Need help with high ec

[Aqua Man]

Will this do, can get it Tomorrow

Yup that's perfect

 

[Lewish02]

Can use it in a pinch but I would definitely order something else.

Don't use more than a tsp per 5 gal.

Its usually just a tiny amount i use, I mostly get my ph down to 5.6-5.7 then add a small amount. I've no had time to read that ph article ill do it just now.

 

[Lewish02]

Yeah but you likely have low buffering capacity and that will create an unstable ph and large ph swings.

Cannabis can tolerate a fair bit but does better in a more stable environment.

Should I buy a coco buffering agent and also my intake ph is about 6 and runoff which I just tested again is 6.7

No just do it with your feed... you can add buffering to the media but then your stuck with what you add if you make a mistake.

Hi mate, I've been watering them once per day with 20% runoff. My inlet ec is 2.1, ppm is about 1100. The ec in runoff is 3.1. I've tried lowering the feed which brings it down but I'm starting to see deficiencies. The ph is 6-6.2 and runoff ph is 6.4-6.5. You any idea whats causing it all plants look healthy except 1 which I think the leaves are canoeing down. Cheers.

I’ve got canoeing upwards , I’ve lowered my intake to 1.4 ec and run off is 1.8ec that’s for week 6 flowering. I’m still seeing very dark green leaves on some areas .

Ive no got a clue its my first grow. I'm in week 4 of flower, do I not need to flush them. Cheers

I flushed with straight ph water then the next day went to half strength nutes . Been a few days since I did this . My ppm / ec is good now but some leaves dark green still

Ok mate cool, is it flush 3x size of pot. Hope you get them sorted.

Hope so mate . I just ran 8litres though . Not even sure the size of my pots

I've just finished flushing 35 Ltr each with just under 0.8 ec strength nutes as its coco. Ec is still 1.8 in runoff but better than way up at 3.2. I've nuked them lol

Have pics?

I water my coco often to prevent this and feeding over 800ppm if synthetic nutrients are used is likely to add issues.

Yeah I'm watering them using that method u said to do. 5% of pot volume 20%runoff. Think my ppm was around 950-100

Only once a day is needed at that size?

What size pots again?

You can definitely reduce the nutrients to 600-800ppm

40ltr pots

I'll reduce the ppm tomoz, giving them big bud at 2mll/ltr will I reduce that too or just calmag and flora series nutes

Use the ratios as described by the company then dilute it down to your desired ppm

I didn't give that a thought. I just gave them less. Nice one thanks
