Yellowing -> brown spots leaves - old Nitrogen def.?

P.S. Don't have a pH meter yet, though I saw a five buck one for gardening in the store which I'll prob. pick up.

If it's an analog one that you stick in the soil then I would recommend you don't bother. Get an electric one off ebay or a hydro store.

I use an oakton myself. I think it's great. I'm looking at getting a tds meter for my next grow :thumbsup:
