If its a true soilless, you want ph closer to 5.8

I’m not familiar with that brand of coco, but ph should be lower in coco like @HornHead said :v::bear:

So you should be good with your PH. I have used their coco and it’s lovely stuff. They make products at least as good as the Fox Farms products IMO.

I personally believe after doing years of experiments and projects that coco and soil-less needs a PH over 6.1. anything between 6.1 and 6.5 is in range. 5.8 is too low, despite past references being made to that along with some manufacturer guidelines.

For my self. I would rather see my run off high like that as to low. my plants just seem to do better. I ph in at 6 my self and normally get run off in the 5.8 - 6.1 range. I also have found. my run off numbers are higher for a while if I did the first rinse of the coco with plain tap water. it normally takes me close to 8 weeks for the numbers to settle down around 5.8 - 6.0 since I do my first rinse with straight tap water. That doesn’t mean I am doing it right. just what I found works with the coco I use.

You are correct. Even though its coco based, the microbes need a ph of 6.1-6.5 to thrive.

Good looking out. I normally bounce my pH around a little bit so the plant can absorb all the nutrients but I’ll give it a shot I’ll switch it up to 6.2

I’m not understanding why my ph in the gelato keeps climbing to 7.0! It cant be lockout, I haven’t used any nutrients yet. Did a flush last night to get the ph in range, today right back at 7.0! Any advice?

Top dress with lime? That ought to buffer it.

Good idea. The Nectar for the Gods has lime in their ph up. My ppm’s are getting low enough to start nutrients. Maybe when I start giving nutrients, the ph will stabilize.
