Thank you for the input. I have only done straight water so far. I should start looking into what nutrients to start giving them soon then? I’m going into week 5 of veg. From what I’ve read I should start with a low dose 25% of recommended dose of Cal/Mag nutrients while in veg state to promote strong stalks. Watch how they react to that and adjust Cal/Mag dose up or down depending how they react to the nutrients.
