all organic soil, and i dnt think its nute burn since i started with very very very low dosage. Im starting to suspect its nutrient lockout since ive never let 20% of the water runoff so i bet i have some salt build up .

she's getting 18 hours of light. I did a mild nutrient flush ( read in the grow bible to do one once a month) runoff from soil was @ 6.2 and water going in if im I'm not mistaken was also 6.2
