Roots Organics 707 Formula soil is the best soil out there for autoflowers.
Also I would recommend any boost solution for veg state, such as: Buddha Grow by Roots Organics.
Make sure to not overdose your plants with nutrients as this will do way more harm than good.
Happy Growing! :)
@ElChicDelaWeed Hi mate I see you didn't mention any extra aeration material to go with your coconut I can reccomend perlite or similiar substrate and mix
in to your coco 70% coconut 30% perlite or whatever you can find Then you will definately need some form of Calcium and magnesium supplement
Either go with the premade liquids like calimagic or you could use Dolomite lime and epsom salts . Also a grow and bloom mix that also contains lots of iron and calcium both of mix often cause problems during the grow. Hope this answers your question and greetings to you 👍
i have grown everything in coco. with floratrio, calimagic, ripen and now i started adding koolbloom and u can see my results. i think they aren't bad ✌️
Grab some maxigro, maxibloom, and calimagic. It is about the easiest nutrients you can use and they produce some nice buds. They are cheap which is also a bonus. Good luck!
