Heat stress... the canoeing of the leaves... the other problems I'm seeing (early signs of a calcium deficiency and a very light green color) come from your pH which is much too low for a soil grow... get it up between 6.0 and 6.5 otherwise nutrients (like calcium), which are already in any decent cannabis nutrient formula, will not be available to the plant and you'll end up with a deficiency. Solve it now before it starts or need to take more labor-intensive efforts to solve it later..... Good luck...

Brown spots on older fan leaves Spotted some brown spots on 2 of the older fan leaves today. Any thoughts on what the issue may be? Does not rub off- was worried about rust at first. Some more info that could be helpful is that I am using RO water. Thinking about rasing the lights a little higher up too.
