Droopy Leaves!

[troller]

Hello:

Got some fairly decent little bushes going in a couple different BP units, they have been veg'ing about 3 wks or so. As the title of the post states I'm seeing some droopy sad-ass looking leaves on the plants, oddly enough more so later on in the day, whereas earlier in the morning they are kinda perky. Using a 1-10 scale with 1 being perfectly perky and normal and 10 being totally hit and drooping down, I'd say in the morning after the lights off period of 4 hrs, they are maybe a 3 or 4, then degrade in appearance to about a 7 or 8 at the end of their day. Some reading tells me that this would indicate a sign of over-watering, which is a little strange being that its hydro. I was thinking about decreasing the ON time of the water pumps, but thought I'd ask you all first.

Stats: Pumps and air run 100% of the time, MH running 20 on/4 off. About 3/4 of the plants have ample roots in the water, the remaining are a little smaller but have at least a couple roots dipping into the water.

Thank you kindly for the advice.

What are your temps like> Droopy leafs can also come from heat stress. An the way you say they are ok when lights are off leads me to believe this.

Thanks for your reply.

Lights on, temp doesn't exceed 80 F. Lights off, temp no lower than 70 F. The humidity is between 40-45%.

On a side note, after reading Roseman's columns, I have switched the water pump cycling to 1/2 hr ON every 6 hrs. Reservoir temperature has dropped by about 3.5 F. pH has been high for awhile @ 6.7ish (just got my meter the other day!)

Any comments or suggestions my friends??
