Sudden wilting of entire plant, spread to another!!!!

[SuperToker]

Entire plant just collapsed. Never seen anything like this before. Possible cold temperatures 60f at night. Have been going great until now. 1/3 died suddenly, then about a week later another one. Just one left that isn't wilted. What is wrong?

ph has been a little high, but as soon as i corrected it from 8.2 down to 7.5 the next day the second plant wilted, so i'm not sure this is responsible. Possible nutrient lock out? I have flushed with plain water several times, both plants not responding. It is not a root rot or anything like that, the roots like great.

Anyone see this before?

ok, what medium are you using?

How often are you supplying them with water?

8.2 is way to high as is 7.5. Soil uses the highest pH setting which is 6.5-7 MAXIMUM!

Looks like you tried to compensate something by repeated flushing them. Looks like over-watering to me as you tried to change the way they were reacting to your high pH.

Get some ph-down and mix your nutrient solution to be 6.5 if you're using soil!!!! 5.8-6.0 for hydro!!!!

Need more pics of the entire setup etc. Anyway your lines are clogged? or some how the roots got damaged? Did you transplant recently? Are you sure the stems didn't break or they didn't break the roots off by getting spun or moved? Sudden wilting in a plant is usually due to extreme lack of water , possibly extreme overwatering (more like a medium wilt) or damage like root ball breakage, stem breakage, etc that I'm aware of..

hydroton w/ bucket within bucket recirculating system. on continuous drip. last night i turned off the drip completely, and have been watering by hand with plain water. 3 plants same strain. all on same nutrients. i got ph down and just didn't want to change the ph too fast since it was off by so much. for the past month, they have been perfectly fine with the ph, nutes, drip, everything. I haven't changed anything in the past month. 30 days ago i switched from *gulp* PBP to CNS17. with PBP I didn't ever need to correct my PH. So much for saving money on nutrients.


I still think the problem is the cold temperatures. Anyone see this before?

Id say it's a possible combination of a lot of things, lol. In a hydro type system i wouldn't recommend anything over 6.10 pH. I'm only JUST starting my system but the research i've done say 5.6-6.0 for hydro systems.

60f at night would cause some issues, yes. My temps got down to 68-69 at night and some of my plants started to purple. So i guess maybe 65f would be a good low point? Also, how hot does it get during lights on? If there's extreme temps it would cause some problems. Perhaps you could start a reverse light schedule so that they would be one during the night time and off during the day. That would counter act them getting too hot during the day and too cold at night.

Yeah but the plant beside it is fine. And the one that wilted completely wilted, not common for any watered plant, all this points to complete drying out, Were the roots wet? Are the buckets connected? Have you checked the roots? Did they grow into the holes and clog the system? Pics...
