Growing some spring delights

Week 1 veg for Super Kush and is already showing signs of stress, probably from my experimental potting mix 😒. I've been trying to diagnose the issue and I think it's nutrient lockout, which is a bit worrying on the first week! Anyways, have add some cal-mag to the power roots solution and shall see what happens. I'm hoping it will sort itself out once it stretches its roots and becomes larger, but it is a hope. (I really should stop experimenting and thinking I know best! 😂. But where's the fun in that? Running one light at the mo at 30%. Once the 2nd unknown seed becomes established will turn on 2nd light. Not running the carbon extractor at the mo. There's no smell, and not sure if I really need to ventilate that much at this stage...?? Saves me some energy costs. I've gone for a tidier setup, smaller pots because the previous grows' root balls took up hardly any of the 30l pots. I've replanted my carnivores into one trough for easier handling and thought they could all share the same space, make a killer zone for insects 😁.
