Soil

Yeah, not likely you’ll find something that will last the full run without needing a little top up of some kind. I use Gaia green dry amendments for fertilizer, it’s all organic and absolutely idiot proof (virtually impossible to over apply). They make an all purpose 4-4-4 blend that I use for veg, and a 2-8-4 bloom blend for using during flower. Couple spoonfuls per gallon, about every 3-4 weeks and you’re good to go. Nothing else required but water. I mix my own medium, using coco, pearlite, a little worm castings and the Gaia green. Any pre mixed living soil will do you just fine though.

What’s good my bro, I don’t know bout soils car I always use cocos and lightMixes so someone else might be able to shine some light, I’m yet to confirm it but I think that RQS easy boost will carry autos the full way. seems mint so far, my auto is week 5 tomorrow, no problems, toxicities or deficiencies, but am gonna be honest I put a bit more than they recommend, easy as hell too, just ph that water and go lol, hope your all good g feel free to drop me a message✌️

I don't think so. Veg and bloom are different stages which need different nuts. I mainly use biobizz all mix. you are ok for 1st month of life, so 4 weeks. After that you could just integrate some powder in top layer and use only ph water. Using a very rich soil will create deficits during seedlings stage for sure... I used a light mix soil from biobizz with just miccorize + a little bit of root juice and it was enough to see leaves burning on they're tips... adding phed water to 6.2 helped me a lot. The dmged leaves will remain damaged, but newer ones will be ok. I will try out somenew staff after I finish this grow... cheers.
