ohighoanstarted grow question a year ago Looked good til Tues. Noticed leaves curling up, dry crispy. Eco whit read 32%. Thought they needed water from the heat so I gave 1/2 gal per earthbox. Eco whit went to 35%. Max leaf temp 90F and ppfd was 260-320. They look bad today. The 4 in regular pots are looking amazing
