Hi mate, Looks like calcium deficiency due to excessive nitrogen. Exactly what's going on with my plants. I've been trying to correct my nitrogen toxicity for a few feeds with little success. This has started with my plants today, a little less obvious than yours though.
You need to cut the N down a little and feed some cal mag. Careful with the calmag as most seem to contain nitrogen. I'm going to be cutting all sources of N on my plants until they start to turn a little lighter in colour. (Not cutting the calmag obviously)
Hope this helps 🙂

As @inspireme says, my principal error was overwatering that then unbalanced ph that then built up nitrogen that finally blocked calcium.. i lost 30% plants this year for this, only 1 with this problem survived and it's the one in the diary ( she was the best of the worst)

Early flower leaf oddityNoticed odd markings on leaves, some top or mid canopy some below. They vary also - from heat stress, shiny spots, residue from Insecticidal soap or wind burn in odd spots.
I’m about 2 weeks in flowering. Temp was 27 degrees, had to defoliate massive fan leaves... see b4/after
