something wierd happened?

Hi everyone-
About 8 weeks ago, all of our plans started to die. the leaves started dying and drying out. There was no impact to the fish, in fact my husband thought they were growing faster. So we lost most of our lettuce, watercrest, beans and strawberries. We removed all of these plants, replaced them with new ones and everything seems to be back to normal. Does anyone know what would have caused this? I was bummed to have lost all of those plants, I dont understand why it happened.

I wondered if we overcrowded the grow bed? or could it have been from a neighbor's pesticide spray that got on our plants? Just trying to figure out how to prevent this from happening again.

What did your water tests say at the time?

pH?

What about Salt, did you by chance salt the system for any reason?

If your neighbor was spraying pesticide, I'm very glad your fish are all ok but most pesticides don't kill plants.  However if they were spraying herbicides that might kill plants but again, I'm happy your fish survived since herbicides can also do in if it gets into the water heavily enough.

Now depending on you location, heat can do in lettuce and watercress though I would have expected beans to survive heat.  There are also plant diseases that can spread quickly in very densely planted gardens and this tends to be more of a problem in humid climates.
