question on ph ?

[Wheatie]

im using a set of products i got from my local hydro store im growing in coco trying to find the ideal ph for veg and ph for flowering the products im using say that they are ph stable but im getting a reading of 6.8 on both the veg and flower is this right or should i just regulate the ph anyway and go against what the manufacturer recommends ?

I grow in soil with a drip system, I would say 6.8 and 7 being high,that would be a safe range. What does the manufacturer suggest you to keep the ph?

It's probably best not to guess about something as important as pH. There are a couple of us coco growers on the forum and someone will come along with the correct information before too long.

Wheatie: Coco is a hydroponic medium, so you use hydroponic values. Your water/nute solution should be pH 5.7 throughout your grow. (For pH 5.7, 5.6 or 5.8 are acceptable. Just keep it in that range.) You can tweek the pH a little in the last four weeks of flower but, instead of confusing the issue now, just wait until you have four weeks left, then ask again.

Mix your nute solution however you mix it, adjust the pH to 5.7, douse your plants until you have about 10% runoff - if you pour on a liter, 100 ml comes back out of the pot. The 10% runoff doesn't have to be exact, but you want to flood the top part of your pot so that the coco gets a good flush all around each time you water. You water at least once a day. When the plants really want to grow in veg and for all of flower, I water twice per day.

Unless you use either Canna or Biobizz coco, I'd wash the coco with many gallons of fresh water to get all the salt out - just use water from the garden hose for rinsing. You just want to make sure you get all the salt out. EVERY hydro store clerk in the world will tell you that their coco is from inland and not salty but most of the time they don't know where it's from and it IS salty and you need to wash all that salt out.

I'll quit rambling now.

I asked him what the manufacturer suggested. Then the advice may had been abit different. I'll just stay away from the coco questions from now on. I do think ph is important! I did as well say I grew in soil.

cheers fellas most helpful and yes im growing in canna coco so shall i flush it or not ?

Flush it if you suspect that you have salt buildup.
Coco pH should be right around 6- lower than soil- and you need to use a nute designed for coco, or add calmag to your feeding regime, or pre-prep the coco to deal with its bizarre interaction with calcium. I don't really know how to do that, and if I ever grew in coco again I think I'd go with the canna line of nutes for it. Calcium lockout is a real pain to try to treat.
Oh, and check your fert solution pH values AFTER you mix it if you aren't yet.
