Hello all,
I currently grow an LSD 25 Auto in the Aero Plantit DWC system with a reservoir of about 12.5 lt. I am into the second week of growing phase and noticed these brown spots on the first pair of leaves. The light I use is the 144 Marshydro Reflector, the temperature ranges from 23 to 26 max celcius, and the humidity never goes below 55% with top 60 - 63%, the ph due to the DWC, fluctuates from 6.3 when i correct it to 7.2 max. I use the Advanced Nutrients feeding schedule at half strenght (1.2 ml per lt for the base and half for the other) and i add 4 ml in the whole reservoir Ad.NuIMG_20180306_080508.jpg IMG_20180306_080446.jpg IMG_20180306_080457.jpg IMG_20180306_080514.jpg t.
