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.

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.

Yup that's perfect

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 .

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

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
