Need help: Chrystal Rain and Dr. Grinspoon 6 weeks flower

The leaves on the CR have turned brown. Before that, they all got droopy. The leaves on the Dr. G have all gotten droopy. We aren't sure what happened. I think the water pump might have been left off for 2 or 3 days. My friend thinks it got too hot in the room ( it's finally summer here). Nutes were fine and normal. I can't upload pics, but can answer questions... Since this has taken place, we've done a little damage control. Plucked 50% of the water leaves from the CR since they were brown & crispy anyways and cleaned up the Dr. G. They are in DWC 3 gallon black buckets. GH Nutes. The Dr. G has been drinking water normally, but the CR just now needed water. (this took place almost a week ago). We figure, they're not dead yet, so we'll keep our fingers crossed... C
