Day 42 - the leaves with spots appear to be dying, even new leaves have wilted tips.
Day 43 - ph has dropped a bit but the ppm hasn't moved in days. Wondering if I have nutrient lock out.
Day 45 - Growth is good, older leaves still show some rust but new growth seems ok. Added 1L water and reset ph to 6.
Day 46 - looks like it grew an inch overnight!
Day 47 - looks awsome
Day 49 - growth is fantastic
