It is a test-grow so I removed 4 leaves (2 big leaves) for better light penetration with the LST and it doesn't look like it caused stress !
I added coffee grounds and then water and it seems healthy.
Preflowering stage is starting so I think it is the last veg week.
@Mrs_Larimar, oh ok thank you for the info👍 I still prefer bat guano than those bottles that destroys the life in the soil (during quanratine I reuse the soil 😁)
