Every plant is showing new growth, even runty little C.
Staying inside, as snow is sticking around now. Temperature and Rh are harder to control in the hut. Humidity on the greater room windows is going to be an issue, looking into a dehumidifier for the room.
Rotating the pots a quarter turn every 3 days.
@Darkwing101, i can see purplish of stem and this mean P deficiency ... P play an important role, locate carbohydrates in plants on flower sites and is a part of energy cycle to create ATP (molecules that plants destroy to get energy) if there isn't enough P , plants gets a looong flowering period with this results... (little flower) take care about pH, for that Phosphorous and other elements can be absorbed only from 6 to 7 value
May suggest using perlite mixed with your soil on the next grow to get way more air to the roots..that along with watering way less will get you 100% faster better growth..if the soil is consistently wet the roots will not take up nutrients..i understand this is your first grow..trying to save you time..your plants couldve been at that size within 4-5 weeks..this will also help with the RH%..check out the grow boss on youtube..he is a game changer because 80% of the info out there is crap thats why everyone is failing as they say they are winning..it is so easy to be misinformed.. Hope this helps!!
