I'm not an expert. I do think, just looking at the pictures. Is that you should manicure your plant. It should provide better growth for the branches. I manicure my plant at least once a week. And Psymin get some Canna instead.
Gett some Terra Veg. Terra Flores and a small bottle of PK 13-14.
Right now your plant can use some Terra veg. And when it starts to flower, start using the Terra Flores, Both, but only half the dosage of the Terra Veg.
And 4-3 weeks before harvest use the PK 13-14 Only once and then flush.
But use the Terra Veg & Flores still, but at half strengh then. and then the last week just flush, no more nutrients anymore. But First Manicure your plant.
