I have a hydro system with a crop approximately three weeks old. The grow has been going well until my recent res change. I have changed the res three times with no issues. I have been reading about the benifits of oxygen to your roots, and that it was suggested that you disable your constant flow system for awhile to allow the roots to get a higher oxygen intake. Yesterday I emptied my res. I then added three gallons to my six gallon res, with one drop of superthrive. I allowed the system to flush for about 1.5 hrs. After the flush I filled my resevior back up, added nutrients, and made sure the ph was ok, it was- 5.75. Res temp is between 72-80. I have been using the same nutrients with no problems at all. 400w mh 12" from top of the plants, 18/6. Room temps 75-90, humidity averages at about 45%. Bagseed plated in rockwool then hydroton. I did not turn the pump back on for approximately 2.5 hours. Prior to turning the pump on, the plant looked great, about 1.5 hr later my leaves were all droopy. Woke this morning and they were the same way..... anyone have any ideas? Are they ok? I'm kinda stumped cause it looks like overwatering..... in a water system that is supposed to run 24/7...... oh one other thing, My 400w light was not initally directly over the plants, it was to the side over other plants, however the off light was enough for these babies, well I moved the 400w light directly over them and observed them to all get hot (leaves began turning up) so I put the light back to where I had it the first time.
