Thanks Archie!

I realized on Saturday that my digital timer has not been working. The lights have been on 24/7 since Day 1. Ugh. I'm not sure if it's safe to switch to 20/4 or not...

Day 10:

Roots poking through both net pots *

My new 2,000 decibel Vivosun 950 GPH commercial air pump arrived from Amazon today. It works great but needs to move to the crawlspace ASAP

Day 11:

Temp: 74-78
Res temp: 70
Humidity: 40-70%
T5 distance: 7"
Feed: Well
PPM: 155
pH: 5.8-6

The smaller plant has been about a day or two behind from the start. The water level is currently 1/2 inch below the net pots, so I top fed today just in case.

Day 13:

The plants seemed a little droopy after lights on, so I lowered the water level to ~1.5 inches below the net pots.

Res Temp: 70

T5 distance: 6"
Feed: Well water
PPM: 155

Day 16

My res temp is back to 72 degrees under T5 due to warm days. I covered my res lid with eflective tape to keep light out. I don't know if it will help lower the temperature, but it's significantly darker in the res.

Nute schedule starts tomorrow. I'm sticking with GH Flora trio, Armor Si, CaliMagic, and Recharge.

Temp: 74-79
Res temp: 71-72
Humidity: 40-60%
T5 distance: 5"
Feed: Well + 1ml CAL-MAG
PPM: 205
pH: 5.9

Day 17

1ml micro, 1ml grow, 1ml bloom, 1ml CAL-MAG

PPM: 299 (water is 120)
pH: 5.8

EDIT: Wild pH swing last night. It held at 5.8 for at least three hours after I added nutes. Then I woke up at 4am on accident and realized the pH was 7.0. Yikes! PH down to 5.8. Woke up at 9am and it was back to 6.5.

Day 20

Temp: 74-80
Res temp: 72
Humidity: 30-50%
T5 distance: 4-5"

Day 25

I removed the water pump from the res and the temp no longer exceeds 70°. The dual waterfall and circulation was great, but not worth the heat.

Im following the Captain's 3 part, 2 part, 1 part method for GH nutes. This seems to get me close to the ideal PPM for autoflower.
