2024/01/26 : not much to say, mainlining is going on...
2024/01/29 : LST on first nodes and removed second nodes.
2024/02/01 : first tiny signs of deficiencies on lower fan leaves so BB transplanted to a 2 gal smartpot with 70% canna coco pro+ / 20% hydroton / 10% worm-humus and added 1 g monsterX mycorrhizae, 1 g Aptus micromix soil, another half biotabs tablet, 10g startrex watered with 2 L (orgatrex @5 mL/L + 1 g bactrex + calmag @1 mL/L). That should do the trick for next vegetation month. I let it rest for a few days to recover from transplant and I'll do 2nd topping after third nodes. Once main-lining redone with "Js", the height is 13,5 cm.
