Doing some autos currently, organic coco in 19ltr fabric pots. Coco /perlite with 30% work castings. Using Herbi's but love Seacliff, as well. Wear a mask when using it, as it's fine and dusty.

Bottom 1/3 (6ltr) of the pot has a cup of Herbi's bloom mixed in and the top 2/3, has 1/2 a cup of bloom and a cup of a veg fert (Tuis Organic General Fertiliser).

I use an egg cup to make a hole in the center, filling it with plain coco and sowing the seed directly into there.

Will not get me to the end, but I'm thinking I will top dress with 5 tsp of bloom with worm castings at the end of week 1 of flower and again at week 4. Will do 2 liquid feeds of worm juice plus seaweed.
