Greetings all,

I let this plant go a day too long without watering. Is this a sign of nutrient burn? Or could it be ph fluctuation?

I recently flushed the plant. Even though the water I was putting in was ph 7.5, it drained out at 6.2. Previously I have been setting the ph down to about 6.2 before watering (after adding the nutes). Is it possible by doing so I have set the soil ph level too low?

Thanks for any help you can offer.

Peace.

First off, you are using an incorrect ph for coco, and thats the cause of most of your problems. You need to use a way lower ph, around 5.8 (5.6-6 narrow range, 5.3-6.3 wide range).

Aditionally, the water quality maybe causing problems too. Tell us more about it.

As firts treatment, do a flush and finist it watering with nutrient solution at 5.6.

Happy growing

Thanks again for the reply, knna,

The water is from an artisan well. It has been tested as follows:

- ph 7.6-8.0
- ppm < 7
- almost no traces of anything else in the water

I get access to the well about once a week and take about 50L or so (about 10gal), which I keep unmodified until I am ready to use it.

When you say that the nutrient solution should be around 5.6 would that be before going in, or for the runoff?

Thanks.

I refered to the nutrient solution's ph. Run off is a poor reference for ph, it often is only useful to detect is something is very out of range.

Note than the most optimum ph on coco is about 5.8, but i suggested you to use 5.6 to compensate for the high ph you had been running.

BTW, very good water. It will help you growing in coco very much
