What’s wrong with my plants?

Hello all. I left for a week work trip. When I came back I had some browning on the leaves of my plant. The one that looks the worse is a photo period. The second photo is of my auto.

plants are being kept 75 degrees
I flushed the plants with phd water (half tap water half distilled) before I left the then Gave them a light feeding.

any ideal what could be causing this? All input is welcome. Thank you

apologies forgot to add that. Fox farm ocean Forrest/ fox farm trio at 1/3rd strength. Feed twice weekly

When you say half distilled, are you using dehumidifier water? Like padawanwarrior said more info needed.

pH or overfeeding is my guess. Are you adding pH down?

And don't flush unless you know you actually need to.

I am using distilled water from the grocery store. Reason being I’ve been told ppm for tap water may be too high so I mix it with distilled water

Only reason i asked was it may be micro/minor nutrients they are lacking, because of distilled water.

Get a ppm meter and check your tap, or take note of showers and dishwasher, if it spots up its hard water, meaning you got calcium right there in tap, if filters are orange with a well, you got iron. Giving the plant distilled water is robbing it of these essential nutrients.

Use tap .. FFOF is prebuffered , just range ph to 6.5 .
Keep distilled for steam irons … bagged mix doesn’t need “ special water “
