I'm very satisfied with the rapid growth, the smell is also getting stronger!
I'm still using gardening wire to bend the branches for an even canopy. So far it's been working great, but I think I might need to use a trellis net soon though.
*Update three days later:
Installed a trellis net since some of the brances were really taking off, I couldnt hold them more down with steel wires anymore, it would probably crack the stems (like the pictures of the cracked stems, it happened earlier in veg). Cracking the stems even more now would probably stress the plants, and I'm trying to avoid that because they're budding up now.
I keep swapping out the nutrient solution in the reservoir once a week, just to be safe from bacterial growth, mold and so on even though using the product "Athena Cleanse" should prevent that kind of growths.
