I don't know about getting weak but you are talking about a very old plant. Maybe we are just talking old ? Your clones are the same age as the original seed it came from and if you don't know how long it was cloned before you had it then 3+ years. That's old dude. About 2 years me and my bro start running into prob's. Clones get deformed and don't respond good to what it did a year before.

Time for fresh and then you can tell if it's the plants or you. lol
LOC NAR on probation Reviewed by LOC NAR on probation on . HELP!! Thin yellowish-green leaves LOOKING FOR ANY SUGGESTIONS! Im using 5 gallon buckets to do deep water culture growing. Everything SEEMS to be where its supposed to be (ph 5.8, tds about 1200-1400 using straight tapwater, water temp is around 70 degrees, room temp about 75-85 degrees) but for some reason about a week or two into bloom my plants will start getting thin yellowish-green leaves all over. These leaves get thiner and yellower until they're so thin that they dry out and crumble up. The plant is perfectly healthy Rating: 5
