A problem from hell!

I was gonna trash these plants but before i do that i'll just see if anyone can tell me what they think this problem is.

The plants were with my buddy before i brought them home today. He told me they were standing straight up last night and this morning after he did a water change this happened to them. I hadnt checked on the plants in 2 weeks and im incredibly disappointed to see hydroponic plants this small at almost a month old.

I decided to take them home and keep them myself. I didnt check the ph before i dumped all the water out today but i just changed the water and im using a pool/spa ph tester. Anyway i kinda think this is a ph problem but before these go to the trash have a look and tell me if you guys think they can still make it.

You might be able so save them but I doubt it would be worth it. I'd vote no. :(

u could save them but they would never grow the same. +1 vote for no, not worth your time and effort.

btw my plants are usually about that big after 5 days but not as many leaves.

Thinkin' there prity much fucked

They can come back, depends on how hard ya want it.
Get pH RIGHT and keep it STABLE
Drop of superthrive in res
Keep temps steady
Cross fingers....

are these strains irreplaceable?

were they femanized seeds? might turn hermie if they were? might have been dudes from the go? hate to see you jack up your light bill for no reason other than to save em for the hell of it. Then again, may tyrn out to be some of the best shit you ever smoked.

trying to get them to live would develop your skills and knowledge in great amounts.
Use them as an experiment. How much do you REALLY know. Try different things with each one..

+1 for let them live

Well i was about to take a pic of the only survivor but my lights just went off for the night. I'll take a pic in the morning to see what everyone thinks!
