70x70 BCN critical, 200w lumii black

Hi there :o) Leaves are shading and start to feed the flower. I reduce all the nutriens in the tank and now it will grow for 5 days only on Dragon force and atazyme with chcking outcome. My point is to flush all the nutriens from the ground. Last five days (next week) I will mix only fresh water with Ph 6,2 and Ec as low as posible and start to flush the substrrate with Canna Flush for last 4 days, then 2 days dark and the harvest ! Look forward to see the final product :) I will keep You posted comminity! D.
