Well that's a new one on me. Nowhere on the bottle does it say to spray it on anything and I have a feeling you will see more damage before you are done. I was spraying my young plants several times a day with sodium free seltzer water but like a bonehead I didn't check the ph of the stuff first (ph was 3.8) and did some nice damage to some of my leaves. The damaged leaves continued to decline slowly over time even after I discovered the problem and stopped but eventually the plants gave out a lot of healthy new growth and I pruned the dying leaves off so I wouldn't necessarily look for the burned leaves to return to normal. Watch for new, healthy growth and go from there.

They started near the middle of the leaf, in between the veins as a single brown/copper spot. It then quickly progresses into larger brown/copper areas. Eventually taking over the entire leaf. It started on the lower leaves and has been makeing its Rating: 5
