What The Hell! What's Wrong With These?

[rjson]

So my plants are all drooping, the leaves are falling off and just don't look healthy.

Res temps 66-70
PH 5.8-6.2
PPM 1250 running Lucas formula and 150ml h202 every 3 days
Air temp 66-76
Strains are AK-47 and White Widow

This happened last run too so I took every precaution this time. Meticulously cleaned the room and system, used new hydroton and new airstones. I've never had this problem and now 2 times in a row! I can't figure it out. If I lose these I'm going back to dirt because this is rediculous.

they look nute burned to shit to me. try taking your nute down to half strength.

yea i would say the same thing 1250ppms??? on that small of a plant is death... even on a huge plant in rdwc thats usually death??? rdwc needs to have alot lower ppms then other ways of growing...


more is not better... check out the last link in my thread them grew on no more then 600ppm and 200ppm for most of there life... sounds freaking redicoulous i know but if you do it youll be able to stay in hydro....

Damn that's crazy I've run 1250ppm Lucas numerous times and they loved it! Dropping the strength now to see what happens...

Looks nute burned to me as well, If you have run 12500 ppm in the past with these strains then I would recalibrate my PPM meter cause those are nute burned, my guess is your PPM meter is aout of alignment.

Pull, Them or It out, clean the bucket, flush with PH'd water and H202,Leave for a while like a day max. then start again,but this time add half the concentration,if there after the plant looks hungry increase your feed.

This way no matter what the issue,you know exactly whats going on.Basically take the leash back. RDWC is awesome because we can precisely control most schedules.

This is all IMHO,so take or leave.

flush for 4 days then goto half strength of your normal nutes ,no higher then 400 ppms for a week then go from there.

looks like nute burn to me too, but at 1250 with those strains it should be ok ..... flush and cut the nutes by 50% ... also 150 ml H2O2 in what size res ?

 

[rjson]

150ml h202 29% per 80 gal rez

 

[Arthur Dent.]

Yes use H202, all it does is oxidize most things like an antibiotic if you will, clean up the plant pooh and build up.

looks like you've got an undercurrent there, i run a uc12xl and i dont go much above 1000 ppms the whole grow, even in the directions it says use 1/3 - 2/3 strength nutes.

 

[greenmatter]

undercurrent ????

 

[smokedoja]

the Undercurrent is the name of a rdwc system, i recognize it in his pictures, heres a link to their site http://www.cch2o.com

 

[Arthur Dent.]

Id listen to Smokedoja, his system looks too pro,

Holy crap, but I maintain if you try anything a fresh platform to start off is the best platform.

Smokedoja,,, Nice man.....too nice.

Namste :Joint:

WOW I FEEL RETARDED! Ph meter was WAY OUT OF WACK I had been actually keeping the PH at 4.8!!!!!!!

It's been 3 days of correct ph'd straight tap water and they are bouncing back with good lush new growth, only lost 1 plant!

I'd been storing my hanna meter in ph 7 water in the cap as that's how I thought you were to preserve the probe, but according to the PDF file it says I need a storage solution.

So where should I go from here? Another day in the phd water then dump both res and fill with new water and nutes at 6-700 ppm or just add nutes to this water?
