problems in coco

first pic is before secobd pic is after I flushed looks worse no ??

what your feeding would be pretty helpful to know.

canna a and b and rhizotonic to the exact ammount stated in the regular feed for canna

do you know the npk of those? they do look a little light in color but i think the second picture looks a little better. to me it looks a little hungry for something.

a is 4.0.1 b is 1.4.2 I use the canna feeding chart for this and my ec is 1.1 ph 5.8

one thing is after I flushed I noticed brown spots on some leaves

check out this thread its for the first pic was when I originally got help https://www.rollitup.org/t/nutrient-problem-in-coco.860153/page-3#post-11309615
