Nice training! Will get very bushy shorty!
I personally use top dressing with dry organic amendments.
I grow in 70% coco, 25% worm castings, and 5% perlite with my Organic dry amendments mixed in. watering with dechlorinated tap water with pH between 6.2 - 6.8.
This is very cost efficient and quality effective. Also you don't have to spend hours upon hours mixing synthetic bottle nutrients together. this way we are feeding the bacterial and fungal web in the soil that helps plants uptake proper nutrients when they call upon them instead of guessing how much they need and when they need them. This is the only way I prefer plant medicine is organically.also much better for our beloved planet ☺️✌️
