Double Grape - HLG QB V2 R-Spec

WEEK 6: LET HER GROW DAY 37: RE-PINNED AND WATERED * It took a full 2L of pH'd tap water today without any runoff. I'd love to see an X-ray view of the roots. I bet they are really starting to fill the pot. * I removed all the pins that I use for LST and this allowed me to get under the plant, water around the main stem and remove some of the smaller lower leaves. * I did some light defoliation and pinned all the branches that I could out as far as they would go. It's spreading out rather than growing up. I can live with that. * Lowered the light a bit over 1 inch. It is now 21 inches above the canopy. It should be getting 500-600 PPFD, which I understand is good for flowering. I'll keep an eye on it for any hint of stress. * I continue to monitor VPD. The temperature is 77F, the humidity at 55 and the leaf temp is 72F. This gives me a solid VPD of 0.94. It's been stable there for a few days now. DAY 40: TOP DRESSED AND ENVIRONMENT OUT OF CONTROL * I thought the plants looked a little nutrient imbalanced, so I top dressed. * Based on the advice from the makers of Nature's Living Soil I topped dressed today with a bit more of their mix and a dusting of Mycrohizae. They suggested doing it every two weeks during bloom. Scratched it into the top of the soil and watered in with about 500ml of molasses water. * Total watering of 2L tap water pH'd to 6.4. * My Vivosun oscillating fan failed yesterday. Don't know why. Just unplugged it and it refused to run when I plugged it back in. But, Vivosun provided a great response and in less than 24-hours a new one is on the way. I purchased from Amazon and provided the order number. A good reason to buy from an authorized dealer. * I installed a piece of shelving to the ceiling today. It allows me a lot of flexibility in how I hang my light and anything else. I've turned my light 90-degrees. I think that will even out the footprint for an 18 x 18 grow area where I should be able to keep two plants growing and get into harvesting every 30-to-40 days. * The fan failure and change in my house temperature has really thrown my environment out of control. * l lowered the light to 20-inches above the plants. I will wait a few more days and move it down another inch. I will stop lowering it when I get to 18 inches above the plants. This is based on published PPFD charts from HLG and some reviewers. I am always watching for signs that the light is getting too low. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ TOP TIP: Only use one meter to measure anything. I had two thermometers and two humidity gauges. They never agreed! Neither was accurate enough to provide the same reading. Just caused confusion. Your mileage may vary! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ DAY 43: STILL BLOOMING * Nothing significant to report. No watering since my last report. * Since my fan failed it was difficult to get the VPD stable, but I think I have it. I am currently maintaining it at about 1.0. I will let it creep up over the next week or so. * My replacement fan should be here by the end of the week. ==> Back this weekend for my first Week 7 report. <==
