Lower leaves turning yellow and getting crispyLower leaves are still turning yellow/brown. See photo. A couple weeks ago I got a greenhouse to protect the plant from the rain. Outside temperature has been lower and there hasn't been much sun (mostly clouds) so I don't think heat is a problem anymore. Don't know the pH. Help!Week 5

Leaf DiscolourationI notice some leaves developing this yellow discoloration on the older growth, usually closer to the central stalk than the outside. The green gradually shifts to yellow going from mid leaf outward to the tip. I'm hoping it's just lack of sunlight from the dense foliage. Ideas?Leaves. Color - Yellow

Yellow and fragile leaves 2 weekCouple leaves yellowing and bit curved up. I suggest there can be the options: 1) magnesium deficiency; 2) nitrogen deficiency; 3) Light burn.
For case it is magnesium deficiency I sprayed the leaves with magnesium sulfate (solution - 1g per 1 liter), but it won't help.Leaves. Edges burnt
