HELP... brown spots everywhere

Hey Ninja! You stated in your diary that your ppm are almost up at 2000.They may as well be at that point. That’s way too high and you can see major leaf tip burn and curl. What your looking at is a calcium deficiency induced by nutrient lock out 🔒. You will notice that the spotting isn’t found in shaded parts of plant reinforcing a cal def. This deficiency is known to cause plants to become more susceptible to heat stress and judging by how curled up the leaf edges are on your plant ,(could saw a 2x4) either I’m right or your diary’s temp info is wrong cause 26 degrees should be perfect. To make matters worse, she is probably drinking too much water/nutrients trying to stay cool which further compounds the situation. That, and only 40% RH driving up your VPD. She doesn’t seem to have many brown pistils yet so you might have time to flush using ph balanced water with around 600-800 ppm of bloom nutrient. Make lots of it and keep passing it through your soil until what you put in is what comes out. Good luck! Hope this all makes sense! Cheers 🍻
