2/8 (day 43 flower) Full drain and fill today. Replaced CO2 as well. Plants are maturing at different speeds so harvest will be interesting to say the least. After seeing the stress nanners from late last week, I decided to leave the nutriemts at a slightly elevated level until closer to the end of week 7. Top off nutrients are right around 450ppm. 2/9 (day 44 flower) Had to support one branch with a wooden dowel on the back left plant. The buds on that plant are getting so large and heavy. It is making the branches lean over other colas and block the light. This is why I decided to support it slightly, but I think the branches could support more before truly snapping - just not interested in pushing the limits and obscuring other buds. 2/12 (day 47 flower) Adding supports where needed for heavy colas that are toppling over. Trying to keep the canopy from falling over and creating humidity concerns during these last few days of flower. Buds are nice and dense covered in trichomes! Reservoir PPM is very stable along with pH - a nice change from last grow where my pH was swinging wildly. 2/14 (day 49 flower) PPM of the reservoir is rising when checking in the evening (650ppm), indicating it is no longer up taking nutrients at the same rate - time to begin the flush. Full drain and fill of the reservoir during the evening, 350ppm, 6.1 pH after drain and fill. Top off water will be strictly pH adjusted and hydro guard. Buds are getting heavy, so working to manage the weight and stability of the canopy. As seen by the extra strings and dowel rods showing up as the week progressed.
