so my first one is so close to being done or is done not quite sure second she has a lot of leaves that are turning brown tips first and slowly down is this something to worry about this late in the game
Sin duda tienes una quema por exceso de nutrientes
Mi consejo: riega sólo con agua hasta la cosecha y haz que la planta consuma los nutrientes antes de la cosecha
Disfruta de tu cultivo!
Leaves will start browning if the plant is done flowering completely and is still being placed under flowering conditions. Also could need extra nutrients due to high energy expenditure for the final stretch of flowering.
