Chewed up leaves

Jobbiestarted grow question 5y ago

Wondering if I should be concerned? They have just entered flowering, I have noticed a few leaves bearing this issue. I use ties which have ripped some leaves due to me not being gentle, and I spray a mild cannacure solition regularly.

It looks like the leaf tips and parts of the leaves have burned due to moisture. I suspect that regular spraying has left some water on the leaves. This acts like little lenses for the light. With strong light exposure, the water from the nutrient solution evaporates, and the salt concentration in the leaf increases, drawing water out of the leaf tissue. Eventually, it can even lead to burn damage, like leaf necrosis.
