Pound Town Auto (DWC, cabinet, first grow)

I think last week of veg, but don't really know what I'm talking about. Seemed to get past veg/pre-flower closer to the end of the week. 2/23/24, res was swapped and wiped down. It read at: pH 5.95, 942us, 669 ppm, .47sal directly after. Nutes were 1/8 manufacturer recommended dose Grow, and 1/4 recommended Bloom. 2/25/24, res read: pH 5.8, 832us, 590 ppm, .42sal, 68 F. 2/27/24, one gallon of nute water added. Gallon had 2ml Grow A, 2ml Grow B, 4ml Bloom A, and 4ml Bloom B. An hour later with the pump on, the res read: pH 5.93, 758us, 539 ppm, .38sal, and 68.5 F. 2/28/24, 16 hours after the last reading, the res read at: pH 6.13, 690us, 492 ppm, .34sal, and 68.2 F. Light raised to ~20" on 2/24/24. It was set to 9 and read at 450ppfd or ~32.5dli. On 2/27/24, a small dehumidifier was added (Pro Breeze 16oz.) as well as a small heater (Lasko MyHeat 200W) and both connected to an Inkbird temperature and humidity controller. The heater is set to off regardless as temps seemed to be rising right before I got it. The dehumidifier is likely underpowered, but given the space I have to work with, I couldn't find many options. Humidity remains a big problem, usually staying in the lowish 60s. Inline fan running at 6.
