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".

1.5ec seems a bit low for photoperiod plants, they may want more but before doing that check its PH. Give that they are in soil you may want to raise PH up to 6.4-6.8. Best Of Luck!

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