have 8 plants been going good then four days ago I noticed bottom leaves rolls ng up and inward then crispy.
Now two of them look bad.
I pulled them out. But worried.
Pic 1 first plant
Pic2 second plant
I am watered last night, look so worse.
Pic 3,4,5 are the others plants
Pic6 did notice this on the leaf of healthier plants.
PS did use a foliar spray Cal mag + b1 pH 5.5 twice a week, last done 5 days ago.
Any advice, greatly appreciated.
