BPP & BK RDWC 1st ever grow

Week 2 full strength feed schedule. I change water weekly, week 3 will begin 1/20/24. Hooked water chiller up to system, works great holding water temps at 66-68 deg F. Ph bounced around but has held steady at 5.9 for 4 days now. EC is 1.2. Lights are at 50% intensity. Roots really starting to show. Sorry pics and diary are a little disorganized, didn’t get diary going right away, I’ll keep up to date as week 3 begins. Humidity fluctuates and drops rapidly when the tent is opened. Put a pitcher of room temp water in with the girls to try to keep humidity up, just had a cold snap here with extreme lows! Girls are powering through no prob though 💪 As of 1/18/24 I’ll add update pics daily, also going to phase out hydroguard in favor or SoAg when it arrives in the mail. 1 8ox bottle of SoAg will make almost 50 gallons of “Hydroguard” and it’s much more effective from what I’ve been hearing from others.
