This week consists of July 23, 2022 thru July 29, 2022 - Seeds were planted on May 27th, 2022 and they all sprouted on May 31st, 2022 (~4 days)
Continued on schedule of 2 times do feed and then one water with only PH'd water.
LIGHTS:
I'm running the lights on an 18-6 schedule. I have the dark time scheduled from 11am to 5pm since the lights increase temperature and during that time the outside temperature is at its highest so it seems to be easier to maintain proper temperature ranges with the light off during that period. Swapped out the metal halide bulb to the high pressure sodium on July 6th since the plants have been in flower.
WATER:
July 23rd:
~1500 ml of 6.1 PH and 1500 PPM.
30 ml/gal of Big Bloom
0 ml/gal of Grow Big
15 ml/gal of Tiger Bloom
0 ml/gal of Cal-Mag
July 25th:
~1200 ml of 6.1 PH and oxygenated water
July 27th:
~1500 ml of 6.1 PH and 1500 PPM.
30 ml/gal of Big Bloom
0 ml/gal of Grow Big
15 ml/gal of Tiger Bloom
0 ml/gal of Cal-Mag
July 29th:
~1500 ml of 6.1 PH and 1500 PPM.
30 ml/gal of Big Bloom
0 ml/gal of Grow Big
15 ml/gal of Tiger Bloom
5 ml/gal of Cal-Mag
TEMP/HUMIDITY:
A max of 90.0F and a min of 62.8F with an average of 78.8F.
VPD was harder to maintain this week since it was in the high 80s and low 90s outside with the average being around 1.59.
Whole week numbers>
Temp - 78.8F avg - 62.8F min - 90.0F max
Humidity - 52.7% avg - 21.0% min - 83% max
VPD - 1.59 avg - 0.40 min - 3.20 max
CO2:
Floating ball is between .5 and 1. This lets a more gradual amount of CO2 to enter the tent and I now get a more stable level of CO2 that fluctuates between around 1000 ppm and 1300 ppm. The regulator is still plugged into the same outlet as the lights so it turns off on the same light/dark schedule.
PAR:
PPFD between 300-1500. The tops of some plants are getting the 1200-1400 range and some side leaves are getting in the 400-700 range.
ISSUES:
Nothing new.
TECHNIQUES:
I implemented some minor defoliation on some of the affected leaves and some leaf tucking.
