Magnesium, then? Check your PH to see if lockout is occuring.

Magnesium is one of the easiest deficiencies to tellâ?¦ the green veins along with the yellowness of the entire surrounding leave is a dead giveaway, but sometimes thatâ??s not always the case here. In case you have one of those where it doesnâ??t show the green veins, sometimes leaf tips and edges may discolor and curl upward. The growing tips can turn lime green when the deficiency progresses to the top of the plant. The edges will feel like dry and crispy and usually affects the lower leaves in younger plants, then will affect the middle to upper half when it gets older, but It can also happen on older leaves as well. The deficiency will start at the tip then will take over the entire outer left and right sides of the leaves. The inner part will be yellow and or brownish in color, followed by leaves falling without withering. The tips can also twist and turn as well as curving upwards as if you curl your tongues.
Sound like your plants?
