Anyone else left their indoor grow in the hands of someone else whilst away? My plants look sad… 🫩

My reapers began flowering and fruiting right as I left for Thailand for 4 weeks for a fight. I left my plants in the hands of my grandfather. He has not been feeding them like I showed him and they are turning extremely yellow. I dont want to get angry at him because he is doing me a favour by looking after all my indoor and outdoor plants. but man its sad to see them so yellow… had anyone else had their plants neglected or ruined by their temporary carers? Share your horror stories… 😂 i can't wait to get home to fix them.
