Can help with a high ph problem.I,m growing in 16 liter pots filled with canna coco fiber following the full canna feeding program.I,m watering an hour after lights on by hand an keeping my ph at 5.7.After every third day i just feed water with a ph off 5.7.Every time the run off reads 6.6 should i be flushing the medium more often or lowering the ph of the feed each day to compensate.Any advice would be much appretiated.
PH ?

try using a lower ph of 5 and see what the run off is. It will come down for you with a few applications.

And IMO you shouldn't do that. Worry about the PH going in, not the PH coming out. Coco does funny things to the runoff numbers. Keep your water/nutes going in between 5.5 and 6.2 for coco and you should be good. Are the plants telling you there's a problem, or are you just worried about the runoff numbers?
Just worried about numbers, the plant look as healthy as could be.heard somthing about nutrient lock up and it made me panic abit its my first time growing in coco.So worrie whats goin in and not whats coming out.wHy does the ph of the solution change so much whats the funny things you talk of ?

Your plants are healthy. If they start to look different, then you should worry and figure out what's wrong, but for now keep doing what you're doing. Grow by what your plants tell you, don't grow by numbers.

Coco runoff is not reliable.
However, if the runoff were acidic, I'd worry about overfeeding/anaerobic bacterial growth.

the plants are eating in between the times you are giving it feed, the drift is natural. just as long as the drift is still in the acceptable range for your plants then it shows what they are eating. depending on the nutrients you are using i dont know about canna, when you add nutrients to water they change the ph. if your nutrients mostly lower the ph then if the plant takes them up the ph will rise back up.
mistress says it so much better, correct me if the caveman logic is flawed

Thanks for all the advice! Had never heard of a PH drift.The fact that they look so healthy should be enough for me.They had feed at 5.2PH today but will revert back to 5.7 PH tomorrow.I,m now paranoid i will do more harm than good trying to get the PH back down.thanks again for the reasurance. I will put some pics up tomorrow n people can tell me what they think.

u should never worry about a problem your not having, try to be more gratefull for what u have and see how it affects your garden.
I thought that I would post this again from the Canna website. So many people are trying to measure coco runoff the wrong way and thinking they have a problem.
The most reliable method for measuring the nutrient levels in Coco is using the 1:1.5 extraction method. EC and pH of the root environment can be determined by using this method. The pH and EC of the drain water generally deviates from the actual root situation, as Coco is able to retain and release elements.
1. Take a sample of Coco from the slabs or pots. This can be done with a soil core sampler or a trowel.
To get a representative sample the Coco must be collected from as many places as possible.
2. Put the sample in a bowl and determine whether it contains the right amount of moisture. The Coco has the right amount of moisture if moisture disappears between your fingers when you squeeze it. Add demineralised water if necessary and mix the Coco.
3. Take a 250 ml measuring jug and fill it with 150 ml of demineralised water. Add Coco to the 250 ml mark. Fully mix and allow the slurry to settle for at least two hours.
4. Mix again and measure the pH.
5. Filter this material and measure the EC.

theres an even better way to measure your cocos nute load, look at your plant-

i would normally say the exact same thing castel, but i am a lazy sob. watching and monitoring those levels inside the media can prevent the need to wait for physical signs to show. but then again how do you get to know what the plants preferences until you see with your eyes what it is they do not like.
interesting mindfuck lol
once you know your plants preferences by seeing things, knowing why can never hurt then next time we can nip it in da bud

You do not have a PH problem. Just keep doing what you have been doing. Stop checking the runoff. In my opinion you are doing well.
