hello i m having a big bud regular in day 19 from seedling and 3-4 days now some of the higher leaves are smole and twisted. i have good temperatures 68(light off) 75-76(lights on). 1-85watt cfl 2700k 1-85watt cfl 6400. I have also good ventilation. I m watering every 5 days for 300ml and the last two times i used: the first time 0.1 ml rootjuice and the second 0.15ml rootjuice and 0.15ml biogrow. I use distiled water with ph 6.5-6.8. Any idea why are the leaves twisted?
