You’re running the wrong pH for Coco @Spots

The pH needs to be 5.8 for soiless growing mediums!

I’d also recommend you follow the feeding chart for your nutrients. They should be getting nutrients at least once a week, every week!

Maybe I got that wrong
This is the medium I transplanted her into 6+ weeks back

I transplanted because I had started in a slow release fertiliser that wasn’t meant for cannabis, worked ok for early vege I thought.

The bloom nutes I have don’t have a chart, it’s just bat guano stuff the grow shop sold me.

Can you post the ingredients from the bag? Coco is organic too. @Spots

Thanks @bob31

This is best I can do for medium ingredients, the website on bag doesn’t open, the bag doesn’t state ingredients, so that’s a screenshot from site I bought it off.

It is organic, but it is peat based and not a soil. It does have dolomite lime to adjust the pH.

So here is what you do. pH a cup of water to 6.5 and add a Tbsp of that soil. Let it sit 10 minutes and check the pH. Let me know the results after you do it @Spots

Another thing that soil mix is treated with neem oil. I imagine it will be worn off by flowering but neem o can affect the flavor of mj. I think it will be fine but I wouldn’t recommend transplanting into that mix.
