Transplant seems to have worked - no real change to the plants.
One of the plants had two yellow and slightly curled leaves, but that started before the transplant. All the other new leaves on this plant look okay, but I'll watch out for it.
Had a short heatwave this week, and the temperatures and humidity soared in the tent 60% RH and 35 C - quite scary!
I aired out the tent by leaving the flap open during "lights-on" hours, and it went down.
I put my dehumidifier in the room (not in the tent) and this helped bring down the RH to 40 before kicking back up to a healthier 50 and the temp went back to 29 C.
Adjusted my ventilation ducts too to ensure that more cool air can come in, and that hot air can get out.
Added a 0.5 ml/ 1000 ml dilution of Power Roots this week as well.
