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 in veg and the problem does not start until blooom (1000 watt system). This has been the story for a couple of harvest and I cant figure out what the problem is. This is a slow but sure killer and its been like watching my best freinds die a slow death. Has anyone experienced this problem and can you offer me some good advice?

I would suggest root products. I particularly like Rhizotonic and Cannazym.

Not that I'm saying it will fix your problem.....without any pics or fertilizer info it's pretty impossible to say. Fill out the troubleshooting form in plant problems forum and then hopefully someone can give you some actual, useful information. Pics would REALLY help as well.

try posting this in the growing section under plant problems, i'm sure one of the growing experts will be able to help you out. good luck with the grow:jointsmile:

Are you sure those temps are correct? Do you have a fresh air intake?

Ok I've been having a problem with tissue paper thin leaves for about three harvests now. I think I'm doing everything right but no matter what, about a week or two into bloom ALL! my plants start getting thin yellow and eventually burnt crispy leaves. The ones that don't die are stunted. Although I've had several mothers I've had the same strain for about three years now. In the begging everything was great, it was almost too! easy to grow big bushes of buds, now I just cant get it right. A friend suggested I start over from seed because my strain might be getting weak. Another friend told me that strains never get weak. I don't know? Whats the longest you've kept a strain before starting from seed again? Does cloning generation after generation eventually make your plants weaker?
P.S. Three years ago I started from clones so there is no telling what generation I actually started with:rastasmoke:

as far as i know those figure are correct.

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
