Holes in Leaves
I've noticed that all my plants seem to be developing holes in the leaves. These are not being caused by any fish or snails. The holes were not eate there but they almost appear to be caused by a lacking nutirent. Anyone aware of a lack of any nutrient that would cause this? I have been dosing with Flourish Excell but no other liquid ferts. About 2 months ago I also added some Miracle Grow House plant fert sticks however I had noticed the holes even before that.
