I have some plants that I just switched to 12/12 4-5 days ago. I live in a hot area, so I have root rot problems. I changed the water yesterday - 4 gallons of water and I added 2 cups of 3% H202 in addition to the nutes. One plant looked particularly droopy after 45 mins, so I emptied out a 1.5 gallons of the nutes+H202 water and replaced it with ph balanced water without anything else. The droopy plant came back to life and I went to sleep sometime later.

This morning, I checked on the plants, and they look a little droopy. They are in the dark phase now - I keep the lights on at night and off during the day because it gets hot where I live during the day.

Basically, is it okay for plants to get a little droopy during the dark cycle? I've grown before, and I don't remember it happening that much - the stems are upright - it's just that all the leaves are a little droopy on all the plants.

It's been dark for them for 4 hours now.
