Had to do the first res change, brought the ppm to 620+/- . This week was recorded on morning number 11. Roots are starting to come out of the net pots in all 3 plants. Looking forward to next week with a new res change to 800ppm. Update. 4/10 Res change to 850 and ph of 6. Day 18. Will do res change around the 28th to a heavy feed for late veg stage of around 950 to 1000. That will bring me into flower for the 2 blue dreams.
