Another yellow leave issue :-(

[molegrower]

Hey all.. my Barneys LSD isn't doing that great.. it's day 36ish in veg and the poor thing is wilting.
Ppms set at 500
Ph 5.7
Using iconic grow
8ml silica
8 ml cal/mag GH which was just added three days ago. Using ro water and ive never added any before
5ml humic acid
Dwc in a 3.5 bucket..
Everything was looking great.. had a few cold nights.. (dipped in the 40s) and that's when this started to happen.. I was reading cold temps stops N intake.. and thought that with a combo of no cal/mag added was causing this.. this is three days after res change.. with added nutes/additives.. also my flowering girls showing the same issues.. this are set at ppms 900.. all with res changes three days ago. And put into 5gal buckets out of the 3.5 gals.. thanx again all four any help

Wow that needs fixed ASAP! Are they drinking more water then nutes? For example say you do a res change and the PPM's are at 700, when you go to change and test the remaining water the is the PPM's high like into the 1200 range? These numbers can give you an idea if they are drinking more water then nutes or vice versa.

Another example say you did a res change and it was at 700 PPM when you go to do another change and test the remaining water and it comes to 300 PPM you know its drinking more nutes then water. You need to balance this out.

If i was in your situation right now, i would probably res change all of them out and run them for 24 hours on plain RO water with a bit of H2O2, Then dial the PPMs back just a bit and see how much they are drinking of what....

Good luck

Also to add, you might want to calibrate your PH and PPM meters just to be 100 percent sure

Since it not cal mag problem, it that nute lockout?

Thanks so much ill do that.. I picked up the calibration solution today and will be doing that as well..

And yes.. the nute value goes up. I'm thinking my ph own is out of wack.. the more I'm thinking about it.. thanx again.

Well.. my ph meter was off by .8.. running phed ro water for a day took sine of the dead leaves off.. if I can't bring it back ill pull the branches I can clone from..and hope for the best
