Bagseed etc. first grow

The tent is filling up fast! I built and installed my new COB and Far Red LED lights this week, then flipped to 12/12 40 days after I popped seeds. I'm running the far red LED for 20 minutes a day, 5 minutes before lights off to 15 minutes after lights off. Plants are loving the extra 300W...they almost doubled in size! Topping and HST were successful; next grow I will do this again only I will top earlier and 2-3 times (sativas). Tent temp got down to 61 one night I forgot to turn the heater back on. Humidity levels are getting hard to keep below 70%. I'm still venting the tent only by aiming a small fan at a duct opening. I'll try to get my blower and carbon can set up next week. I chased pH values around , pH was found to be low (5.5) early and again late in Week 6. Stable again at 5.8-5.9. DWC water temps OK between 66 and 72 degrees, Changed nutes late in the week. Running GH nutes per week 5 of their DWC schedule: Plants are looking good and appear to be healthy and happy. Got some root porn photos at the end of veg cycle! It looks as if my largest, most interesting plant, Vortex #1, is a female. I hope to be finish sexing the plants and thin out the garden by next week.
