White Truffles S1 / Apex R1

V36 to 42 Monday Got some trays so I can start manually bottom feeding them in case my autopots aren't ready. Since I started they really picked up. My brand new pH pen just broke again so it would explain the slow growth and yellowish leaves. I ended up switching brands that lets me replace the probes. Tired of dealing with that especially since the bluelab pens are wildly expensive now. My TDS meter also broke and so I'm feeding blind too. It should hopefully get here this week. Thinking I buy a backup exhaust and some other stuff since everything has been getting used for over 2 years now... Exciting times. 750ppm (I think?) @ 5.8 25c/65rh Lights ~23k lux.
