PC Grow - Blueberry

Week 3 Vegetation Start of week three veg, we have some growth but also some problems! The RH has been super low here being winter, with the average of 30% in the house. I have been using a large ziploc bag with holes over the plant about half the day to try and keep humidity up while lights are on. I have noticed the lower leaves have started to dry up and crumble, top of the plant is starting to turn yellow a little. Not happy about something. I didn't use RO water this res change but used tap water... My tap water is 200ppm and ph 7.5. After mixing nutes I ended up 600ppm and pH 5.9. Not sure if I am underfeeding or...? Still new to hydro. 12/02/2020 - Noticing lower leaves are getting dry and crispy. - Also starting to fade in colour to a yellow 12/03/2020 - Replaced res with RO water and nutes, seems to be doing better. I believe the pH was drifting on me. 12/04/2020 - Starting to grow quicker again. 12/05/2020 - No change. 12/06/2020 - Topped plant 12/07/2020 - No change. 12/08/2020 - No change. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ENCLOSURE - Antec 300 PC Case LIGHTS - 8x 6.5W LED strip - 3000k, 85CRI, 24VDC VENTILATION - 80x80mm pc fan for intake, 12VDC - 120x120mm pc fan for light exhaust, 12VDC - 120x120mm pc fan for exhaust with carbon filters, 12VDC - Activated carbon sheets - Remote thermometer/hygrometer DWC - Air pump #1 - 1L/min - Air pump #2 - 0.5L/min - Digital thermometer - Bluelab Truncheon nutrient meter - pH pen WATER - Tap water - 2mL/L Advanced pH Micro - 2mL/L Advanced pH Grow - 2mL/L GHE Flora Bloom ENVIRONMENT Room Temp: 25 °C Humidity: 70% ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ All comments and critiques are welcome!
