Grow Mediums Coco & Soil Question

[BHGz]

Hey guys so I have a question about a coco/soil mix I'm about to do. I was going to do the canuk way of growing which obviously didnt work due to obvious reasons. I have the 70/30 mix of mother earth coco perlite 50liters and I added 10 tbsp of down to earth veg 4-4-4 & 3 tbsp bloom 4-8-4 to the coco. Now I want to mix in a 50liter bag of Happy tree frog for a 50/50mix. I have watered the coco a few times trying to get some seeds going but not alot. Now will the soil be too hot for germinating and planting a seed into a rapid rooter, then transplanting into the 50/50 mix with the DTE dry amendments or will it be okay?

Did you get it sorted out

Others can inform you better, but it seems dangerous mixing coco/perlite and soil in 50:50 range. You may end up with both coco- and soil-associated problems, and others too. For example, will you target pH for coco or soil?

Also, why load-up your mixture with fertilizer vs. wait and see and give what is needed?

I just went with Happy Tree Frog by itself, didn't want to risk burning my girls.

Tbh I was going with a method that's been tested and proven not good. I just wanted to add the coco in so I didn't waste any money or nutrients. Did some digging and saw that people add a low percentage of coco coir into their soils. I went with happy tree frog which is a decently hot soil so I didn't want to risk burning my girls. I still have my coco coir with the DTE in it but I think I'm going to flush out the dry nutes with run off and test the ppms after a few washes.
