Anybody know what the problem is with these...?

Anybody have an idea as to what the problem might be wrong with my plants? Any feedback is appreciated. I'm thinking it might be heat stress? My room does tend to run on the warm side at about 85 and high humidity of about 60 - 70%.

Looks like light burn. Move your lamp away and see if that works

Especially if the problem is occurring more at the top of the plant.

heat stroke and chem burn. You feeding the one in the cup too?

ask for advice then split I guess, mabe he had an apiphamy?

Raise light and give theose girls some water. The soil looks awful dry. Put a small fan blowing between the tops and the light.

im thinking the same soil looks dry especally if room running warm drying out soil put pail of water in front of fan poor mans cooling and humitafer

The top of the soil drys out quickly due to the fans blowing on the plants. But when you stick your finger down in a half inch to an inch, it's still nice and damp. Lights are above the plants by about 3 feet at least so I don't thnk it can be light burn - plus I'm just running two TEC lights with 8 bulbs each. And the problem with the leaves is not just at the top, but all throughout the plant.

the clone in the cup has NOT been fed so It can't be nutrient burn. And I don't think humidity is the problem as it is running between 60 and 70 percent.

Any more thoughts?

By the way, sorry I didnt get back earlier, rollitup.org didn't notify me by email that you guys had replied
