Original Sour Diesel - coco grow

Light power consumption: 230 watt Hi there fellow growers! This update covers the week from 28 November to 4 December. This is the first week the plants are on a 12/12 light schedule. It was another good week of growing without any complications. On day 50 I did another LST session, to spread out the branches and open up the plants. I also increased the light power consumption to 230 watt. During the week, the girls increased their growth rate significantly: the flowering stretch has commenced! The whole system is now in full swing: the automated fertigation system delivers a fresh batch of nutes five times a day with ~15% run off. Consequently, the coco is >95% saturated all the time. Due to this frequent fertigation, an EC of 1,1 mS/cm is still more than sufficient, as all the nutrients are delivered five times a day in the correct ratio’s. I’m still using the growth formula, as the plants need a lot of nitrogen during the stretch. Nevertheless, at the end of the week, I noticed run off EC dropped to 0,6 mS/cm, which is 0,5 mS/cm below inflow. This indicated two things: the nutrient ratios of the fertigation mix are spot on, but there is also room to increase the EC. I’m aiming for a run off EC that’s no more than 0,3 mS/cm under the inflow EC. One or two times this week, I also fertigated by hand and gave them a full CalMag dose at target EC with a bit of Terra Aquatica’s Silicate. On day 56, the last day of the week, I did another aggressive training session to flat out the canopy. I also defoliated quite a bit, to make sure that light penetrated to all those side shoots. And last, I also pruned some sideshoots from which it was already clear they are not going to make it to the top of the canopy. That’s all for this week. Thanks for stopping by and happy growing!
