Issue with droopy leaves.

The setup is Hydro. Nutrients are fox farms. PH is 6.2. Temp is 73-78. light is 600w MH running at 50%. Water level is about 1" up the basket. Just moved it from T5 to the MH a few days ago. Not thinking when I turned it on, it had the HPS bulb in it for about an hour before I came back and realized it. The plant looked fine at the time, but later that night the leaves started to droop and curl down. Any Ideas out there?

No clue. How is the air flow? It looks like nut problems but I dint know. How close is the HID compared to the T5s? Good luck.

You said you switch from a T5 to MH?If so, heat stress? What is the temp of the canopy?

now the temp is fine, but when the HPS was on, I'm sure it was quite a bit hotter. It didn't show any sings until several hours after i switched out the bulbs to the cooler mh though.

In the first place for hydro ph should be 5.8, and I tend to agree it might be heat stress.

Thanks for the help folks. I dropped the PH and I'll give it some time to recover. Hopefully she will bounce back for me.

I swear that MH are hotter than HPS kill me if im wrong. But running a hps in veg for a hour won't do anything bad.
