Calcium questions.

[Sean420mac]

Im having a little issue with spotting leaves towards the top of my plant. The spots are little brown spots and mostly on the edge of the leaves. I nelieve this is due to lack of calcium. Whats a good way from home supplies to boost up calcium levels? I nedd to act quickly please.

is it a lack of calcium, or a pH issue preventing your plant from accessing calcium that's already there?

What's your growing medium?
What's your pH of water going in?
What's your runoff pH?
What nutrients are you using, and how often?

Dolomite Lime, if you've got any around the house.
