I sprayed my lawn (hose-end sprayer) with a liquid lawn fertilizer (20-3-4) and some over-spray probably got on a few potted tomato plants. The area was heavily watered the day before.
The next day I noticed the tomato plants looked somewhat shriveled without actually being wilted or droopy.
The fertilizer contained no herbicide or weed killer. Just 20% nitrogen, 3% Phosphorus (Phosphoric acid) and 4% soluble potash. Would something like this be harmful to tomato plants?
