Browning, curling of Green Crack leaves

happykatstarted grow question 4y ago

Is this discoloration worrisome? Ph 6.1, adding 1tsp calmag to each gal, EC at 1.5. What's causing this browning? Seeing only on the Green Crack, mostly higher leaves, but some lower too. Does it need more or less of something? Leaves look "dirty".

@gmslave, do you think it's a calmag overdose?

Hello. When I watered 3 days ago, I saw some brown spots on the lower leaves and thought I had got some nutrient solution on the leaves but now it's on the next set too. Any idea what is going on? All 3 plants are being treated the same. Thanks Chuck.

Bottom Leaves only looking worse for wear Hi, does anyone know what's causing some of my very lowest leaves to become like this? They are still attached to the plant but fall off really easily and look like they've had the life sucked out of them. The rest of the plant looks relatively fine.
