This is light stress, move your light up a bit or lower the wattage a tad, had the same issue. Leave will curl in an attempt to lower the amount of photons received.

High, this is caused by heatstress. Try to lower down the temperature and move the lamp 10 cm further away from the plant!

So... the brown spots in the last 2 photos. Are they Ca deficiency? Will I do extra damage if I add Ca/mG supplement? What is the upper concentration of Ca/Mg concentration for cannabis in DWC grow? How can I tell if I add too much Ca/Mg? Help please!

Nutrient problem?Hi growers not sure what this is as it's only on a few leaves but a few brown spots have appeared and I have quite a few purple stems, don't no if it's a strain trait or if it's phos deficiency or something else, any advice would be welcome, growing in live organic soil.

I am not sure what’s going on with plant A (pictures above). Does this look like a CalMag deficiency? The CalMag at 5mls per gallon seems to be working but I’d love to know what some of you other growers think? Thank you for reading this post and thanks for any advice given. 🙏
