Update
Flower time!
pH pen arrived last night at 6pm. Mixed up foop at specs for week one. Nice minty smell BUT after a bit if you get any on your hands it smells like you cleaned a bunch of fish. I have never disliked that smell as so have some good memories of cleaning a wheelbarrow of Perch as a young man.
Flipped to 12-12 today. Flipped spectrum to flower. Once again the increase in spectrum increased the lux this time to 40k at the same power setting of 80%
Plants are on 5 gallon buckets and this gives me 20 inches to the lights. Additional fan in floor of tent swirls the humidity that lays low like a cloud bank.
Now for some surprising information.
I am pretty sure my ACI heater box is defective. It is on top of the tent in warmer air and it will increase the temp by 11 degrees. I added a stoner engineered ceramic heater under a 24x30 box box nestled up against the heat. I put growee sensor in the 4 inch duct from this fresh air source.
Well I did some number crunching with power use at the outlet. The ceramic heater using 240 watts produces a 100 degree airflow at the tent bottom. The ACI on high uses 420 watts and on setting 8........420 watts. Specs state 530 watts at full power.
Test was tent from open door reset to 80 degrees. Lung room at tent top 69 degrees. Lung room on floor 62 degrees. Ran ceramic heater only then heat box only.
Heat box alone raised temp to 80 in 21 minutes. Ceramic heater in a cardboard box raised it in 18 minutes. Remember heat box had been on floor for the first 5 weeks and the numbers would have been worse. Running both resets to 80 in 9 minutes.
After this grow is done I will look into ACI's awesome warranty.
Tent was also expanded with plastic clothes hangers in the corners. The middle and upper portions of the tent are prolly close to 36 inches with just this little trick
Plan is raising lux to 55 k over a 2 week period. Right now new growth is reaching for the light. I believe I only have another 2 weeks where I can pull plants out to train. After that I will place pots at back of tent oriented to train to front of tent.
Numbers 40k lux. Light 20 inches from Tops. Temp 85. vdp 1.2
pH nutes 6.25 ( new pen with 2 digit sig fig accuracy) duct set 2 during day 3 during night. Fans setting 4 and plants doing the dance.
First pic damaged leaves from running low on nutes.

Second pic white widow 48 days above ground
Will continue to monitor leaf damage as it may take a while for the organic nutes to start uptake.
