I think your plants really look pretty cute yo. Just showing signs of heat and ph stress.

What were your runoff ph's? For all those waterings. Are you in the danger zone? Im not familiar with liquid tests so I dont know what the colors correspond to.

Also, dont assume your soil is not buffering at all just because your ph was the same going out as it was going in. Could be your soil was very near to that ph already!

Oh, and youll be a lucky gardener that has all your plants on the exact same watering schedule. I do a constant grow, and its a headache trying to keep track of everyone!
