I'm using 100% coco and the lights are 11hrs on and 13 off and with 13hrs lights off it extendeds the drying period of the coco and that will dry out the coco more and also increase EC but also maybe the uptake is not happening as much as before and that will also increase the EC in the coco...current EC input is 0.9 and checking runoff today it has increase to 1.6EC it was only 1.3 a few days ago so it seems to be going in the increase EC direction and the amount off runoff is the same as before so its adequate...i thinking of dropping my nutrient below 0.9 or just put more watering into to lower EC runoff its at day 45 with maybe 5-6 days to go for harvest.
