Irie Genetics -- Mystery Test Seeds

04/05/22 - Notes (Day 15) * Still In Solo Cups * No sign of roots towards outer edge of cup yet. * Humidifier is not keeping up * PPFD 450 / DLI 29.16 -------------------------------------------------------- 04/06/22 - Notes (Day 16) * Changed out Humidifier, and adjusted airflow to help with VPD issues. * VPD: 1.4 at leaf top - way too high for early veg.) * VPD should be: - Propagation / Early Veg Stage 0.4 - 0.8 kPa - Late Veg / Early Flower Stage 0.8 - 1.2 kPa - Mid / Late Flower Stage 1.2 - 1.6 kPa - Danger Zone Below 0.4 / Over 1.6 * Transplanted all 5 to the final pot * They now feed off of AutoPot Rez (I'll top feed if needed) * Rez: 6.17 pH * Rez: 2.11 EC * PPFD: 450 / DLI: 29.16 * I'm moving them closer to 35 DLI each day. * They'll get 40 DLI in flower -------------------------------------------------------- 04/07/22 - Notes (Day 17) * I was able to raise the RH%, but still not enough. * VPD: 1.3 at the leaf (too high) * Solution: When the Previous Harvest is Dry - Add a 2nd Humidifier. Temps are mostly mid-70s * The reservoir is dialed in: -- EC: 2.0 -- pH: 6.01 -------------------------------------------------------- 04/08/22 - Notes (Day 18) Nothing significant See Day 18 Stats Graphic (Included with Day 19 Stats) -------------------------------------------------------- 04/09/22 - Notes (Day 19) Day 19 - Stats & Notes * Sill slightly high with VPD * But, I think today is a trim day on the last harvest. * This means a second humidifier is coming to the rescue. * Flip to Flower Day is set (for now): 04/26/2022 for 12/12 lighting. * As you can see by my Tent Limitations Graphic, I may change Flip-To-Flower if certain height limitations come into play. * If somehow these plants get to 34" from the bottom of the tent before then, I'll flip sooner. * This decision still allows for 28 inches of stretch before light-contact issues. -------------------------------------------------------- Day 21 (04/11/2022) - End of Week 2 of Veg VPD Issues: * VPD still too high. Not Dangerous though. * Added the second humidifier to help with VPD Ugly Leaves: * Original damaged leaves now look like Ca or P deficiency * Each plant will get a 250ml mixture of Cal/Mag The Rez: * pH had risen to 6.86 from 6.21 * I used 16 ml of pH Down to get to 5.98 * I don't mind the drift because I think it opens more nutrient doors at different pH levels. * This is the lowest I have taken it. * Plan to go to 5.8 pH and let drift up with the next nutrient addition. * After all adjustments, the E.C. is now 1.95. Coco Coir: * This is my first grow with coco * I buffered it well with Calcium Nitrate per Jack's Nutrients instructions * That's why I was surprised if this is true Ca deficiency AutoPots - Bottom Watering: * Also, this is my first run with bottom-watering AutoPots. * I will continue feeding on the top for a while longer -------------------------------------------------------- Day 22 (04/12/2022) - Begin Week 3 of Veg Cal/Mag: I gave a lite dose (100 ml) to counter the apparent calcium deficiency. Calcium Nitrate: To help with yellowing leaves I gave them Nitrogen and Calcium via Calcium Nitrate Dose: 0.150 EC (approx 75 ppm) AutoPots: My guess is that the bottom-up feeding hasn't met with the roots yet. VPD: VPD is improved since adding the second humidifier I adjusted them to reach for 65% since 60% was barely getting the tent to maintain 54% RH If I maintain a leaf temperature around 75ºF, I need between 64 - 66% RH. DLI: Maintaining around 35 DLI until flower. Although, I am likely to start edging up soon. There are still 2 more weeks until the flip
