I have 4 PK clones in promix hp with worm castings, bat guano, some lime to bring the ph to 6.5 thats what all 4 are reading i dont know exact age 5 weeks maybe new growth is turning light green and fan leaves are turing purple starting from the outside in. New growth looks soft, temps have been between 18 degrees celsius to 25 during the day and as low as 7 at night.
