Hi Growmies, I'd like to ask you about spots on leaves shown on photo Already moved my led higher, slowed down the circulating fan - but that also may be a calmag deficiency(?) Fast version (7 week) strain in the middle of 6th bloom week Appears mostly on tops Organic biobizz

At this stage it might just be senescence or 68F and below temps when lights go off, if occuring. the fact it is happening in shielded spots makes it less likely to be light-related, so you can go ahead and revert those changes unles something else was apart of that decision. do have some tip burn, so just make sure that doesn't progress to fast. Canopy is strong, you have time to be patient. I bet this turns out to be some red/purple leaves - like autumn outside and for the same causes.

Far too late to "fix" anything now, but it looks like a combination of not enough calcium and too much feeding in general with some burning evident. Don't worry about this plant, you are so close to harvest that there is nothing you can do now to solve/change anything. Remember, what is showing in the leaves now, is a direct reflection of what was happening in the root zone 2-3 weeks ago.

Hey 👋 In the first moment I agree with mistaOC, looks like calcium. But in general your plant appears to be very dark green, with burned tips. So this could be also the first signs of a nutrience burn if I do not mistaken 🧐

If your pH level is within the optimal range and you can rule out pH-related issues, I would suspect a calcium deficiency. The brown to bronze-colored spots strongly suggest a lack of calcium – assuming everything else is in order.
