Thanks, carcass.I think the upcoming cooler weather will solve the problem...your plants actually look damn good, even with the heat they've been in.
I'm battling heat too,been 86f in the box for the last two days-they say cooler weather is coming-I'll believe it when I see it...
Of note: i gave a relatively light watering Monday night to the three in fabric pots and pH'd it to 6.5 using vinegar. The top and sides were where I concentrated the watering as those were dry. The NL and OS leaves felt dry and a little crinkly prior to watering. Not as much today. One more hot day with 90 degree temps and then the cooling trend begins.
