Cream Auto 2 phenotypes

✋Wk 2: Germination progress, fertigation, and a new light. 👉Today is day 14 fro the 3gallon pot and day 10 for the 1 gallon. The one gallon has outpaced the 3 gallon plant in growth. It stretched a little and is 3times the relative size of the one in the 3 gallon. Im not sure how this will affect my plan to grow a smaller plant in the smaller pot. Both seedlings are looking good. There was a little yellow on the cotyledon of the 3 gallon seed. Up until 3 days ago, I was just moistening the area around the plant 2x a day with pH water that had a very small amount of Flora blend. The EC was .2ms. pH was 6.0. So 3 days ago I initiated fertigation to saturate the entire pot and get at least 30% runoff. This is to keep the pH coco as stable and in range (5.5-6.3Ph) as possible. The 1 gallon is getting the simple program of nutrients on the General Hydroponics drain to waste feed chart diluted to the low end of the recommended EC range and possibly lower. The 3 gallon will be getting the expert program of nutrients on the same chart mixed to be at the mid to upper end of the charts recommended EC. My pH target is to average 5.9. Both are on week one and will change to week two by midweek. I think that I probably have two different phenotypes at play here and I don't know If Ill stick to this plan for both plants. I dont plan on doing any topping, fimming, lst etc. I plan on just doing leaf tucking and providing support for the branches if they need it and shape the plant a little. 👉I got my second MarsHydro TS1000 led today and installed it. Each light is approx 150w draw and I have them at 75%. I remove the 300w COB and right away the temperature dropped from 78 in the tent to 76. The COB when compared to the MarsH has the same LUX output, at twice the wattage and lots more heat so its inefficient. 👉 I still haven't closed off the side vent window yet, which is allowing unrestricted air flow into the tent. I have the one 4" inflow, the 6"exhaust, one small oscillating fan and one 6" fan pointed at the lights. I will ad a second 4" inflow fan and a second ceiling pointed 6" fan pointed at the lights. When I do this I will close the vent window and hopefully have slight negative pressure in the tent. Too much negative will cause the sides to suck in and cause unnecessary stress on the ten. The 6" exhaust is on a variable controller and currently set at its lowest speed. I think I will have more control and create more stable temperatures when the plants are in the flower mode. When they are flowering the outdoor temperatures will be mild, and the house HVAC wont run as much. Last year it was a problem and contributed to bud rot on the critical purple. I do have a better understanding of how to set the HVAC to control the temps and I also will have far less wattage being used in the tent with the leds. Last year during spring I had 3 lights going for a total of 900w. My last plant was grown with just 300w total and that's what this one will use. The new lights are a little brighter than the phlyzons they replace. I may remove the ballast and mount them outside the tent but only if heat is an issue.
