Northern Light by RQS

Hello my fellow growers! Thanks for stopping by. So first of all, I have been wondering about the volume of my pot and found this online calculator: https://www.orangepippintrees.co.uk/plant-pot-calculator.aspx I found out that my pot is smaller than I thought so I updated the pot volume in the diary here. I will definitely use a bigger one in the future, considering I always only grow one plant per time. That being said, I was fearing mold last week but I found out that it was just some "early purpeling" as someone in the grow answers told me. In any case that encouraged me to increase air circulation so I'm thankful for the scare. Last week I started supplementing with RQS easy bloom booster tablets (kind gift from RQS) and I'm continuing with that. My lower fan leaves are yellowing and started to show rust spots (probably signs of Ca/Mg deficiency) so I think this will help, I'm still unexperienced so hopefully my diagnosis correct. In general I try to keep some lower fan leaves since they can be early indicators of toxicity/deficency issues that need to be fixed. Overall I'm satisfied with how things are progressing! I don't think my girl will grow in height much more, she's 40cm tall and though I would have loved a bigger plant but I guess the pot is too small. Thanks for reading and come back soon for more updates 😎👋
