Hey 👋 From the picture, it looks like a classic calcium deficiency. So you need CalMag to fix it. I would actually add it to the water every time you water to prevent such deficiencies (unfortunately, this almost always happens under LEDs without CalMag). Sensi has a pretty good overview of the top deficiencies. I'll post the link for you, then you can compare and read up on what specifically helps with your deficiency to fix it: https://sensiseeds.com/de/blog/wie-man-die-sieben-haufigsten-defizite-von-cannabispflanzen-anhand-von-blattsymptomen-erkennt/ Hope that helps a bit. Have fun growing 👊🍀

Hi shinweed! 👋 I'm not sure how accurate your diary information is, but based on metrics you use I'd say water is cycling far too slow, 66f nights with 72f days. Transpiration is the daytime process that pulls water up through the plant from the rootzones. In order for the plant to transpire efficiently the environment must promote evaporation. Plant will transpire 3x at 86f than it does at 68f. Transpiration and the amount of osmotic pressure will dictate nutrient uptake rate. Nutrients are the building supplies. Symptoms indicate : nutrient deficiency or mechanism which transports minerals is crippled due to any other environmental metric, oversaturated soil, high rh, Best of luck buddyyy.
