Gorilla Glue Auto Tent Grow

Seedlings are continuing to stack and replicate at this stage, albeit a bit slowly it seems for almost 3 weeks from germination. I'm thinking I was a bit too conservative with the power level on my light but wanted to take a it slowly as figured out how the plants would react to different power levels. Switched to a 20 on 4 off light schedule and increased power to 70%. Lowering humidity at this stage to about 55% The left plant appears a bit lighter in the pictures but it is not as dramatic in person. Started to water a bit more aggressively this week with a full soak from a PH'd watering can every other day. Fortunately fabric pots with a raised tray are very forgiving to over-watering but I'm thinking I need to let the soil dry out more between watering. Learning how to use the "lifting method" to get a sense for how heavy a dry pot is vs a pot still full of moisture. Applied neem oil as a preventive measure at this stage. Lightly misted all leaves (top and bottom) and the top soil using the directions on my bottle.
