OOOOHHHHH NNNNOOOOO...so here is what i think...since i gave up hydro because of this happening to me a few times...If you want to save these plants and are tired of checking and rechecking, and unchecking...go out a buy a bag of Fox Farms Ocean Soil, and then figure the ph of your tap water and if it is close to 7 then just use it with nothing added...Putting them in soil now would get them going, and give you time to fiure all the hudro stuff out...it is tough...and every plant is different., Some people on here make it look so easy, but they don't give any useful tips when your garden is lying in ruin...Anyway it isn't that easy...so go grab some soil---Fox Farms Roots Organics, Some good quality organic potting soil all you have to do is water them...it is hard to get wrong...and you can build your confidence and abilities back up. True story...I had 4 doing this same thing because something at some point haywire...a piece of lint fell in a bucket and turned into microscopic encephalitis...I don't know,b ut some shit would happen and everything would die...like this *snaps fingers*! Anyway I had 4 doing this same thing in hydro...so after trying for a year to do this and getting weirdo little stuntling half dead plants I gave up...went and bought some soil and some nursery pots---all plant nurseries carry good quality soils, and will usually give you a few nursery pots if you inquire to buy some...anyway I took these 4 mostly dead plants, 2 were around 3 weeks to a month of veg, and the other 2 were 5 weeks flower...I started with 1 feminized seed so I couldn't just say eff it...so I took all of them except the largest one that was just too far gone...and I stuck them in the soil...if I couldn't get them out of their net pots I stuck it in there too and just buried it all...watered them and in 2 weeks the ones that had been vegging weren't even recognizable as being the same plants....they had leaves and looked good...the one that remained from 5 weeks flowering looked crazy cuz then it had to reveg...and now it is almost ready to harvest and has been successfully cloned and everything keeps on keeping on...my garden looks great! It isn't depressing like it used to be..instead of feeling like a failure I feel very successful in my recent endeavors..and since everything has been looking nice I felt confident enough to get some new seeds, and am getting ready to harvest one of the new plants as well... So, If you really want to save them and are tired of cominginand finding everything dead then make that easy leap to soil.
