You've got a temperature range of 20°± and an RH range of 15%. That's a lot.
What are your temps and RH values daytime and nighttime? Temperature + RH => vapor pressure deficit = how fast water is leaving your plant = how fast water is going into your plant.
When the vapor pressure deficit is high, meaning that it's hot and dry to the plant, the plant has to take up a lot of water. If you're taking up a lot of water you can get a nute issue (calcium?) that looks like a deficiency but it's just an imbalance.
I don't Overthink Shit when comes a winter auto's . I'm tired of all These Rookies, who think that a VPD is Then and & End all of a freaking Grow.. Spend some and find for in Unfavorable Conditions. Grow your own for few years. Then learn on Your own Accord!You've got a temperature range of 20°± and an RH range of 15%. That's a lot.
